Expert Answer:

To find the square root of a number, find the prime factorisation of the number.
To understand this, let us take an example.
We shall find the square root of the number, 324.
This is how we find the prime factorisation of 324.
that is 324 = 2 × 2 × 3 × 3 × 3 × 3
 
You can see that each of the prime factors occurs twice the number of times it occurs in the prime factorisation of the number itself.
So, we pair the prime factors 
begin mathsize 16px style 324 space equals space stack stack 2 space cross times space 2 with underbrace below with blank below space cross times stack stack space 3 space cross times space 3 with underbrace below with blank below space cross times stack stack space 3 space cross times space 3 with underbrace below with blank below
So comma space square root of 324 space equals space 2 space cross times space 3 space cross times space 3
left parenthesis that space is comma space remove space one space of space the space numbers space from space each space pair right parenthesis
The space product space is space the space square space root.
So comma space square root of 324 space equals space 2 space cross times space 3 space cross times space 3 space equals space 18
Hope space this space helps factorial factorial end style
