Solution - Simplifying square roots

Simplify :  sqrt(8000) 

Factor 8000 into its prime factors
           8000 = 2⁶ • 5³ 

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 :
           1600 = 2⁶ • 5² 

Factors which will remain inside the root are :
           5 = 5 

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 :
           40 = 2³ • 5 

The simplified SQRT looks like this:
         40 • sqrt (5)
