SUMMARY

The discussion centers on the simplification of the expression \(\frac{px^{p-1}}{q(x^{p/q})^{q-1}}\) to arrive at the correct answer \(\frac{px^{p/q-1}}{q}\). The user initially attempted the solution by manipulating the expression but made an error by not properly handling the \(x\) in the denominator. The key takeaway is the importance of correctly managing exponents during simplification, particularly when transitioning terms between the numerator and denominator.

PREREQUISITES
  • Understanding of algebraic manipulation and exponent rules
  • Familiarity with rational expressions
  • Basic knowledge of polynomial functions
  • Experience with simplifying fractions in algebra

Homework Statement



[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]

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
