5y^8125
*you have to factor completley
easy. Take out the five:
5(y^825)
Now, isnt y^{8} the same as y^{4} )^{2} ? That is a square, so you have that y^{4} squared minus another perfect square? That factor as the difference of two squares. After doing that, you may have another difference of squares to factor.
So would it be 5(y^25)
