derivative of

f (x) = e^{- 5 x^{4}}

- 20 e^{- 5 x^{4}} x^{3}

Solution steps

\frac{d}{d x} (e^{- 5 x^{4}})

Apply the chain rule:

e^{- 5 x^{4}} \frac{d}{d x} (- 5 x^{4})

= e^{- 5 x^{4}} \frac{d}{d x} (- 5 x^{4})

\frac{d}{d x} (- 5 x^{4}) = - 20 x^{3}

= e^{- 5 x^{4}} (- 20 x^{3})

Simplify

= - 20 e^{- 5 x^{4}} x^{3}
