\frac{d}{d x} (a x e^{4 x})

a (e^{4 x} + 4 e^{4 x} x)

Solution steps

\frac{d}{d x} (a x e^{4 x})

Take the constant out:

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

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = e^{4 x}

= a (\frac{d x}{d x} e^{4 x} + \frac{d}{d x} (e^{4 x}) x)

\frac{d x}{d x} = 1

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

= a (1 \cdot e^{4 x} + e^{4 x} \cdot 4 x)

Simplify

= a (e^{4 x} + 4 e^{4 x} x)
