Rewrite the rational exponent as a radical. a.3radacal5 to the power of 2 b.12radical5 c. radical 5 d.3 radical 3 to the power of 4

Rule of exponents:  (5^a)^b = 5^(ab)

Thus,      3
              ---
               4
           5           to the power 2/3 is 

     
              6/12            1/2
            5              = 5         = √5
