   2/ 2    \
log \x  + 1/

$$\log{\left(x^{2} + 1 \right)}^{2}$$

log(x^2 + 1)^2

Detail solution

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

$\frac{4 x \log{\left(x^{2} + 1 \right)}}{x^{2} + 1}$
Now simplify:

$\frac{4 x \log{\left(x^{2} + 1 \right)}}{x^{2} + 1}$

The answer is:

$\frac{4 x \log{\left(x^{2} + 1 \right)}}{x^{2} + 1}$
