#-y^7#

Explanation:

We can factor out the negative to make things look a bit nicer for the simplification of exponents.

#-(y^5)(y^2)#

Recall that #x^ax^b=x^(a+b)#. In other words, when multiplying terms with the same base and different exponents, you can combine everything into one term and add the exponents.

Then, we have

#-(y^(5+2))=-y^7#
