For Comparison
In order to rid the denominator of the surd/square root  , we rationalize it . 
Rationalizing is the process whereby we multiply the denominator by another fraction with the numerator and denominator like it . We make use of the identities such as : (a+b)^2 = a^2 + 2ab + b^2 ,
(a-b)^2 = a^2-2ab+b^2 or (a+b)(a-b) = a^2-b^2 

Recall : Prime factorization 
It is a way of breaking down a compound number into  prime factors
