Solution - Simplifying square roots

Simplify :  sqrt(1331) 

Factor 1331 into its prime factors
           1331 = 11³ 

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 :
           121 = 11² 

Factors which will remain inside the root are :
           11 = 11 

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 :
           11 = 11 

The simplified SQRT looks like this:
         11 • sqrt (11)
