The solution

     /    3 ___\
x*log\1 + \/ x /

$$x \log{\left(\sqrt[3]{x} + 1 \right)}$$

x*log(1 + x^(1/3))

Detail solution

Apply the product rule:

$\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$

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

$\frac{\frac{\sqrt[3]{x}}{3} + \left(\sqrt[3]{x} + 1\right) \log{\left(\sqrt[3]{x} + 1 \right)}}{\sqrt[3]{x} + 1}$

The answer is:

$\frac{\frac{\sqrt[3]{x}}{3} + \left(\sqrt[3]{x} + 1\right) \log{\left(\sqrt[3]{x} + 1 \right)}}{\sqrt[3]{x} + 1}$
