36 = 2 × 2 × 3 × 3

Now,

we make groups of two

 

Finding Square root through prime factorisation - Part 2

So,

  Square root of 36 = 2 × 3

       = 6

 

Square root of 49

Finding Square root through prime factorisation - Part 3

 

So, Square root of 49 = 7

 

Square root of 64

Finding Square root through prime factorisation - Part 4

So, Square root of 64 = 2 × 2 × 2

    = 8

 

Square root of 324

Finding Square root through prime factorisation - Part 5

So, Square root of 324 = 2 × 3 × 3

    = 18
