Homework Help: Simplification of factor expresion

  1. Nov 11, 2011 #1
    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.

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