$$\log{\left(x^{2} \right)}$$

log(x^2)

Detail solution

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

$\frac{2}{x}$

The answer is:

$\frac{2}{x}$
