## Homework Statement

Use the product rule to show that dx^n-1/dx = (n-1)x^n-2

## Homework Equations

The general idea is..

If: h(x) = f(x)g(x)

Then: dh(x)/dx = f(x)dg(x)/dx + g(x)df(x)/d(x)

## The Attempt at a Solution

It seems like a simple solution but everytime I attempt solving it I get confused and end up with a totally wrong answer
