log(x)^5

Detail solution

Let $u = \log{\left(x \right)}$ .
Apply the power rule: $u^{5}$ goes to $5 u^{4}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x \right)}$ :
1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
The result of the chain rule is:

$\frac{5 \log{\left(x \right)}^{4}}{x}$

The answer is:

$\frac{5 \log{\left(x \right)}^{4}}{x}$
