Solution - Simplifying square roots

Simplify :  sqrt(24) 

Factor 24 into its prime factors
           24 = 2³ • 3 

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :
           4 = 2² 

Factors which will remain inside the root are :
           6 = 2 • 3 

To complete the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :
           2 = 2 

The simplified SQRT looks like this:
         2 • sqrt (6)
