Explain similarities between radicals and rational 
exponent notation?

There are two ways to express a rational exponent 
as a radical or vice-versa:

FIRST WAY:
            
xa/b = bÖ xa


SECOND WAY:
            
xa/b = (bÖ x )a


The second way is the best way to begin a problem.  
Then after it is simplified the first way is the best 
way to leave the answer.
