Simplification of factor expresion

[mindauggas]

Homework Statement

\frac{px^{p-1}}{q(x^{p/q})^{q-1}}

The answear in the book:

\frac{px^{p/q-1}}{q}

The Attempt at a Solution

(1) \frac{p*x^{p}*x^{-1}}{q*(x^{p/q})^{q}*(x^{p/q})^{-1}}

(2) \frac{px^{p/q}}{qx}

Where is my mistake?

P.S. I omited some steps that seemed pretty straight farward.

I see it now ... the x in the denominator has to go to the top ... what an inffuritingly imbecile mistake
