derivative of

7 x e^{x}

7 (e^{x} + e^{x} x)

Solution steps

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

Take the constant out:

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

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

Apply the Product Rule:

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

f = x, g = e^{x}

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

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

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

= 7 (1 \cdot e^{x} + e^{x} x)

Simplify

= 7 (e^{x} + e^{x} x)
