Okay, to start with, we'll write it in a more math way xd
\[(\dfrac {(x \times y)^4} {x^5 \times y^5} ) ^{-3}\]
Now, to simplify this i would recal the property used in the last problem but in the reverse way, so you'll have
\[(\dfrac {(x \times y)^4} {(x \times y)^5} ) ^{-3}\]
This expression can be treated with the division power property (don't know the proper english name)
\[\dfrac { a^n} { a^m} = a^{n-m}\]

Let me see what you get c:
