Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Let $u = x^{3} + x$ .
2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x^{3} + x\right)$ :
  1. Differentiate $x^{3} + x$ term by term:
    1. Apply the power rule: $x$ goes to $1$
    2. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
    The result is: $3 x^{2} + 1$
  The result of the chain rule is:
  
  $\frac{3 x^{2} + 1}{x^{3} + x}$
So, the result is: $\frac{3 x^{2} + 1}{\left(x^{3} + x\right) \log{\left(4 \right)}}$
Now simplify:

$\frac{3 x^{2} + 1}{x \left(x^{2} + 1\right) \log{\left(4 \right)}}$

The answer is:

$\frac{3 x^{2} + 1}{x \left(x^{2} + 1\right) \log{\left(4 \right)}}$
