TRICK! Schriftlich Wurzeln ziehen – Wurzelziehen, Wurzel berechnenJun 21, 2022
hello dear ones, today i brought you an exciting method on how to get the root in writing. I didn't learn it in school, but I discovered it recently, but I think it's a great possibility if you don't have a pocket calculator. you can actually take the roots of numbers no matter how bad it is the procedure itself is similar to written division so of course you also need a bit of practice until you get it really fast so you can do it , But is it worth it. it's not that bad you could decide for yourself if you show mom an introductory example at the beginning of the first game where the numbers are still relatively nice to us the first thing to do is split your number into two packs so start run from the back or start running from the comma if you ran away you start and take the 16 like two packs and then then the 29 and then we're done here for now so take the first packet here in front of the 29 and think between which two numbers squares is 29 and then you only have to know the square numbers up to 100 but normally you have them relatively well in your head but you can also dare to get a little closer so if you say well 3 squared would be three times 3 so 99 is a number squared the summer is still relatively far away 120 there are definitely some that are closer, for example, the five squared yes 25 is fine, it's very close 29 because he se is squared so six times six 36 the 36 is again too big, that means that the 29 is between the 25 times very 52 and between the 36 which then would be six to the power of 2 and here in front we need this for our calculations because the 5 it's actually our first digit of our result and the 25 that we take from our 29 rp here comes this system as in the written division that we see of 29 25 would be 4 and then our next two packets go down to 16 here I'll save everything now there's a new number created 416 and with that you do it now something that I keep repeating which at first was a bit farfetched or something but you get used to it so the procedure we are doing now repeats over and over again the 416 now divides by twice this number that's here the five double animals 10.10 is written there but you fill it with a zero so there's always 0 0 here No matter how much you changed it again now we share it and think about the frequency uence with which the 100 fits in the 416, it is not about the exact value, but in the frequency with which the 100 fits in the 416, that would be four times and this four is already the digit of our result the next one now we have Let's see what we should deduce here as the next one now we are going to multiply this four that we have here it will be x this number here but I already said this green number does not stay at zero now it is changed to this number that came out here at 4 and what you multiply here 4 x 104 becomes 416 this result is reduced here and there and subtracted from it which is handy it is now zero here it comes out as soon as that is the case you are done with the written division and there you have your result, so feel free to write in the comments how easy is the principle you find, we'll check it with the other two examples there you can see it repeating itself over and over again first we do our two packages running from the back it's 29 our first package then the 81 and then the 38 so this pack is just to give you a better overview because it has no real effect now let's take our first pack on the 38 and think that's always just the first step think what square numbers is the 38 we already had the 36 with us six squared and seven squared would be the next largest 49 in the middle is actually the 38 which means these two smallest are important because here the 6 comes here as the first digit rhein and the 36 I will subtract here 38 36 is two and we take the next packet down now it is divided again, that is, the 281 is divided because one likes to make mistakes, so I tried several times, that was then with my head , I always forgot to double the number here so twice six would be 12 and then there's always this green zero at the end now we divide how often 120 goes into 281 would be double that's going to be our next digit here and we have to go back to multi iplicate to know what we have to subtract here twice this number here where the green digit is replaced by these two here he also likes to forget twice 122 would be 244 this is then subtracted from four to eleven is seven from 5 to 83 that is everything and our next package gets smaller the numbers just get bigger it's clear you always have to do a bit of calculation so the procedure takes a long time depending on the number but you still have a chance I think it's ok so 3729 will divide by double this number here as it is here now so 62 x 2 is 124 and the defeated 0 is not forgotten how often the write will fit this number it should work three times we recalculate the three will probably be the number here I say probably because we can see right away sometimes all three will go wrong now let's go back x this number here where we also replaced the green with the three ourselves, 1243 maybe 3 x 1000 first while 3000 is added three times 200 and 600 and then three times 43 is 129 if we add that we get 3729 exactly what we had here which is great because then we have the zero down here and we know that's our result, the numbers don't always add up of course I used square numbers here so you're happy that's great but it adds up Of course you can also use cortal and depending on how exactly you want the result then compute as long as you want and we will see.
I'll do it here first of all, we'll do four. states not up here but first we'll do our two bundles and although starting from the decimal point, right hammer 1 2 bundles, the 29 on the left would be 95, our two bundles, then 31 and then 2 is up here on its own, but that makes a difference nothing so they're not always in two packages it can also be one package but we start the same way we start at the front and think about the 2 between which are the square numbers because they're numbers so small that once we landed the squares back on 1 we both when we learned the quadrigen were already at 4 that means the two lie between 1 and 4 so we have found our numbers which then wander here that once comes here as the first digit in our result and the other 1 we subtract here from the 2 two - 111 very good our next packet is thrown under that and now divides 131 divides by two times this so once there was a movie 2 and the zero don't forget it's attached how often does 20 go into 131 which is six times six will probably be the next digit now let's see it calculates six times now not 20s but the zero is replaced by our six since we just had six times 26 would be 156 if we want to figure this out now we notice the number is somehow a little big this is too big it doesn't apply so if that happened to you then it's the six here it's not the next digit, but we have to make it smaller than you always do before the six gets smaller and the 26 here also gets smaller to 125 so you factor both here by 1 smaller and calculate again if that fits now 5 x 25 equals 125 look ma h alright the 125 is small enough smaller than the number we can subtract that means not the six goes here but the five goes here so that can happen if the numbers are too much big then you have to go smaller and if they still must be too big he just goes smaller at 4 and 24 but the 425 fits yeah it will go down that would be easy oh only six liters left and the next package is withdrawn next bill is gone split 695 split by please here from 15 32 and attached zero you saw 300 in the 695 only twice and the two of us will probably have we already learned here so I know the next digit let's see if it works by making the 300 twice the green zero please replace both then we get to 604 ok the number is small enough we can subtract it from the four up to 510 up to 96 1 and the next two packets go down again, but we also see here that every comma is there as soon as we barely get past that, the comma comes in here, the 29 is still down and we get to a big division 9129 times double what's written here is 304 and the zero attached don't forget how many times it fits here and l 3040 that should work three times we write down the three here I just hope it fits, we count back three times 3000 and the zero is replaced by the three which comes out three times 3000 would be 9000 times three times 43 would be 129 so we get 9129 as the result, that's exactly the number that's written here That means it will add up nicely and we'd already have our result here, so if it hadn't worked now, it would just continue calculating here with zeros, then you could stay down and continue calculating all the time you want. it has decimal places next to it but otherwise that's it the procedure is a clue if i do this division here and get fifteen or something like that as a result so as soon as the result here should be greater than nine you always write a new one as a result so calculate with nines even if it is higher it shouldn't have appeared here but it always can happen so I'm curious if you can get your correct example ma I write in the comments we get along have a wonderful day and until the next video take care
