It's known as the Pythagorean theorem. 3, 4 and 5 are the side lengths of the smallest right triangle that has only whole numbers as sides.

Well 5^2 = 5*5=25
3^2=3*3=9
4^2=4*4=16
3^2 + 4^2 = 25 = 5^2
It's not very difficult to understand.

5²
= 5*5
= 25
3²+4²
= 3*3 + 4*4
= 9 + 16
= 25
Both are 25, so they're equal.

It happens because 3,4 and 5 have the following representations:
5 = (1)^2 + (2)^2, 4 = 2(1)(2) , and 3 = (2)^2 - (1)^2. This forces the 3,4,5 to be a pythagorean triplet because of the
algebraic identity,
(u^2 + v^2)^2 = (2uv)^2 + (u^2 - v^2)^2

It's Triple Phytagorean
5^2 = 4^2 + 3^2
(5*5) = (4*4) + (3*3)
25 = 16 + 9
25 = 25
It's equal!!!!!!! \(^-^)/

yes, this is quite simple.
If u solve 5² you get 25
then 3²+4² means 9 + 16 which is equal to 25
this means 5²=3²+4² is as same as 25= 9+16
hope you got it,
