derivative of

x^{- 8}

- \frac{8}{x ^{9}}

Solution steps

\frac{d}{d x} (x^{- 8})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= - 8 x^{- 8 - 1}

Simplify

- 8 x^{- 8 - 1} : - \frac{8}{x ^{9}}

= - \frac{8}{x ^{9}}

\frac{\partial}{\partial x} (e^{(3 x + 5 y)})

\frac{d}{d x} (x \cdot e^{x} + e^{x})

\frac{d}{d x} ((\frac{x ^{2} + 4}{x ^{2} - 4})^{4})

\int \frac{( x ^{2} - 3 x + 1 )}{x ^{2} + x} d x
