(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

The answear in the book:

[itex]\frac{px^{p/q-1}}{q}[/itex]

3. The attempt at a solution

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

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

Where is my mistake?

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