    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.
