How would I further simplify the following? \(\ \large (1)(r^2+1)^{-\frac{1}{2}}+r(-\frac{1}{2}(r^2+1))^{-\frac{3}{2}}\)

    and you took literally the power rule maybe it would be best to write as \[\frac{1}{\sqrt{r^2+1}}+\frac{r}{2\sqrt{r+1}^3}\]

    now if you want to add these up, multiply the first fraction top and bottom by \[2(r^2+1)\]

    @satellite73 Yup! It's from a product rule! Nice!
