(13root[7] (y^5))/y137y5y

Explanation:

We will express root[7] (y^27y2 as y^(2/7)y27.
In order to make yy to be in an integral exponent, we need to multiply y^(2/7)y27 by y^(5/7)y57 to get y^1y1.
Therefore, we multiply the fraction by y^(5/7)/y^(5/7)y57y57 to get (13y^(5/7))/(y)13y57y
Instead of writing yy raised to a fractional exponent, we use roots.

Therefore, the answer is (13root[7] (y^5))/y137y5y
