hence
Ok i think I see what happened here but I have a question.
When it got to
e^ln(x^-3)
What you did was bring the ln(x^-3) down by taking the ln to do so right? But wouldn't that end up being
ln(x^-3) lne since you have to do ln of something to bring down whatever is in the exponent? Sorry for the stupid questions =/ just really want to understand it.
