# Thread: Derivative using the Power Rule

1. ## Derivative using the Power Rule

So I understand how to use the power rule on nearly all problems, however if someone could explain this one to me I'd greatly appreciate it.

find the derivative of d/x

I know the answer is -d/x^2 but how do you come to get this answer?

Thanks so much

$\displaystyle \frac{d}{x}=dx^{-1}$

Now apply the power rule.
