Ok, here are the two equations I can't seem to solve.

10x^-3 * (5x^-2)^-3/2^4 * x^(3/2)

and

6p^-4 * (4p^3)^-1/p^-5

The answers are x^(3/2)/200 for the first equation and 3/2p^2 for the second equation.

However, I keep coming up with -1250x^(3/2)/16 for the first equation and 1/24p^2 for the second equation. I have a test monday and I need to know how to do these problems...they're frusterating.
