differentiate the function \[\ y=frac{1}{(1-5x)^2} .... I'm getting \[\10(1-5x)^-3 \] my "book" says \[\ -10(1-5x)^-3 \] if the book is wrong again... i'll stop using it! :@ but if i'm wrong, tell me what i did wrong cos there aren't steps in the book, it's just a question and a solution

    \[\frac{dy}{dx}=\frac{d}{dx}(1-5x)^{-2}=-2(1-5x)^{-3}*\frac{d}{dx}(1-5x)=-2(-5)(1-5x)^{-3}\] \[\implies \frac{dy}{dx}=10(1-5x)^{-3}\]
