   2         
log (5*x + 1)

$$\log{\left(5 x + 1 \right)}^{2}$$

log(5*x + 1)^2

Detail solution

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

$\frac{10 \log{\left(5 x + 1 \right)}}{5 x + 1}$
Now simplify:

$\frac{10 \log{\left(5 x + 1 \right)}}{5 x + 1}$

The answer is:

$\frac{10 \log{\left(5 x + 1 \right)}}{5 x + 1}$
