If the expression is

then these are not square roots. The first one is a 3rd root (aka cube root). It represents whatever you cube to get "a". And the second one is a 5th root (what ever you raise to the 5th power to get "a").

To simplify this expression, you do what it says: "write in exponential form." Any radical can be rewritten using fractional exponents:




etc.

Rewriting your radcials with fractional exponents we get:

And the rule for exponents when multiplying like this is to add the exponents. This gives us:

To add the exponents, which are fractions, we need a common denominator:


This may be an acceptable answer. But if you want to rewrite this back in radical form:
