Derivative of x^7*e^x

The solution

You have entered [src]

 7  x
x *E

$$e^{x} x^{7}$$

x^7*E^x

Detail solution

Apply the product rule:

$\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$

$f{\left(x \right)} = x^{7}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. Apply the power rule: $x^{7}$ goes to $7 x^{6}$
$g{\left(x \right)} = e^{x}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. The derivative of $e^{x}$ is itself.
The result is: $x^{7} e^{x} + 7 x^{6} e^{x}$
Now simplify:

$x^{6} \left(x + 7\right) e^{x}$

The answer is:

$x^{6} \left(x + 7\right) e^{x}$
