Answer 2

The results of the given square root and cubes are:

√121 = 11

√900 = 30

∛125 = 5

∛729 = 9

* Square of a number is such that when the given number gets multiplied with itself.

Square root of the resultant gives us the original number.

For example:

A given number x when squared, we get x*x = x^2

Now on finding the square root of the resultant:

√x^2 = x

*Similarly for cubes we multiply with itself two times and to get the original number back we use cube root.

For example:

A given number x when cubed, we get x*x*x = x^3

Now on finding the cube root of the resultant:

∛x^3 = x .
