\frac{d}{d x} (7 e^{- 3 x})

- 21 e^{- 3 x}

Solution steps

\frac{d}{d x} (7 e^{- 3 x})

Take the constant out:

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

= 7 \frac{d}{d x} (e^{- 3 x})

Apply the chain rule:

e^{- 3 x} \frac{d}{d x} (- 3 x)

= e^{- 3 x} \frac{d}{d x} (- 3 x)

\frac{d}{d x} (- 3 x) = - 3

= 7 e^{- 3 x} (- 3)

Simplify

= - 21 e^{- 3 x}
