log(x^2*E^x)

Detail solution

Let $u = e^{x} x^{2}$ .
The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
Then, apply the chain rule. Multiply by $\frac{d}{d x} e^{x} x^{2}$ :
1. Apply the product rule:
  
  $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
  
  $f{\left(x \right)} = x^{2}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Apply the power rule: $x^{2}$ goes to $2 x$
  $g{\left(x \right)} = e^{x}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. The derivative of $e^{x}$ is itself.
  The result is: $x^{2} e^{x} + 2 x e^{x}$
The result of the chain rule is:

$\frac{\left(x^{2} e^{x} + 2 x e^{x}\right) e^{- x}}{x^{2}}$
Now simplify:

$\frac{x + 2}{x}$

The answer is:

$\frac{x + 2}{x}$
