Question 332092: rewrite with positive exponents. assume that even roots are of nonnegative quantities and that all denominators are nonzero.
+4x+%2F+%285%29+sqrt+%28y%29+

I could really use some help with this problem please.

+4x+%2F+%285%29+sqrt+%28y%29+
.
4x/5sqrt(y) * sqrt(y)/sqrt(y) Rationalize the denominator.
=4x*sqrt(y)/5y
=4xy^(1/2)/5y
.
