🔥 Learn an Amazing Maths Square Trick in Seconds! 🔥

This is not true, because it cannot be applied to all roots.

خدعة لكنها لاتنطبق على كل الجذور التربيعية ولو أردت التحقق طبقها على الجذر التربيعي للعدد 144

Why you show is? Its totally bullshit and kiddies: Dont do it! Its wrong. Sqrt49 ≠13-2

solo funciona con esos ejemplos, una tontería

√81 ≠ 7, it equals 9 Don't show these proofs when you can take a random perfect square and it falls apart instantly

Not always true. Sqrt 144 1+4+4=9-2=7 Sqrt 144≠7

¡De haberlos sabido antes! “ ³√125 = ? Según el método mostrado: ³√125 = ? (1 + 2 + 5) - 3 = ? 8 - 3 = ? ? = 5 ✓ 😯

This does not work for all square roots/cubed.

No se cumple para todas las operaciones...raiz 2 de 16..no cumple. Seamos serios en informar..

5

４６の平方根も８で、５２の平方根も５？？

5

great ,,,,, cube root of 125 = (1+2+5)-3=5

If people knew their multiplication tables they would know a lot that on sight.

It’s dumb because it doesn’t process for all data.

1+2+5 = 8-3 = 5

not a rule, pure farming, mathematics hate you

Es un truco que básicamente funciona con las raíces que puso, si quieres un ejemplo hazlo con √49

5

it doesn't work for 9, 16, 36, 49, 81....

一个中国人看得目瞪口呆

This only works on perfect roots

5

1+12+5=18 18-3=15

5

8 + 1=9 9 - 2 = 7 7 X 7 = 81 PERFECT!

奇数階段で暗記しよう。0から最初の奇数は1　1から2段目の奇数3を足すとた4　4に2段目の2で割ると!?そして4に3段目の奇数の5を足して段目の3で割ると!?　そして9に4段目の奇数7を足して4段目の4で割ると!?16に5段目の奇数9を足して5段目の5で割ると!?の階段法則を繰り返してみて

Use the calculator

Amazing!
