When we find the square of an algebraic term, we simply multiply it by itself.

Thus the square of  3a⁴ is   3a⁴ x 3a⁴ = 9a⁸

Or,   (3a⁴)² = 3² x a^4x2 = 9a⁸

The reverse of squaring is finding the square root..

So,  √(9a⁸) = √9 x a^8÷2 = 3a⁴

The steps we need to remember are:

1) √ the number

2) Halve the power.
