Answer 1

Answer:

Square Root :

If x2 = y then we say that square root of y is x and we write √y = x

So, √4 = 2, √9 = 3, √36 = 6

Cube Root:

The cube root of a given number x is the number whose cube is x.

we can say the cube root of x by 3√x

√xy = √x * √y

√x/y = √x / √y = √x / √y x √y / √y = √xy / y.
