\frac{d}{d x} (7 e^{- 5 x})

- 35 e^{- 5 x}

Solution steps

\frac{d}{d x} (7 e^{- 5 x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 7 \frac{d}{d x} (e^{- 5 x})

Apply the chain rule:

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

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

\frac{d}{d x} (- 5 x) = - 5

= 7 e^{- 5 x} (- 5)

Simplify

= - 35 e^{- 5 x}
