Question 367483: Rewrite with positive exponents. Assume that even roots are of nonnegative quantities and that all denominators are nonzero.
+%284q%5E-1%2Fz%5E-3%29%5E-2+

I have +%284z%5E3%2Fq%29%5E-2+ but don't know how to get rid of to the power of -2
Would you divide and get 4z^3/q divided by q/4z^3?
