   / 2    \
log\x  + 5/

$$\log{\left(x^{2} + 5 \right)}$$

log(x^2 + 5)

Detail solution

Let $u = x^{2} + 5$ .
The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x^{2} + 5\right)$ :
1. Differentiate $x^{2} + 5$ term by term:
  1. Apply the power rule: $x^{2}$ goes to $2 x$
  2. The derivative of the constant $5$ is zero.
  The result is: $2 x$
The result of the chain rule is:

$\frac{2 x}{x^{2} + 5}$
Now simplify:

$\frac{2 x}{x^{2} + 5}$

The answer is:

$\frac{2 x}{x^{2} + 5}$
