Answer by ashleygurl92(6)   (Show Source):
You can put this solution on YOUR website! m to the 3rd over mn to the 3rd times n over m in parenthesis to the 4th.
the m to the 3rd over mn to the 3rd stays the same & the n over m in parenthesis to the 4th becomes n to the 4th over m to the 4th.
then, you multiply straight across & get m to the 3rd n to the 4th over m to the 5th n to the 3rd.
then you have to simplify,
m to the 3rd minus m to the 5th & n to the 4th minus n to the 3rd which leaves you with m to the -2nd n & you have to bring the negative to the bottom & when u do that, its not negative anymore so you get n over m to the second.
hope that wasn't too confusing,
