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 a4x2 = 9a8
The reverse of squaring is finding the square root..
So, √(9a8) = √9 x a8÷2 = 3a4
The steps we need to remember are:
1) √ the number
2) Halve the power.
