3 /          2 
\/  x*(x + 1)

$$\sqrt[3]{x \left(x + 1\right)^{2}}$$

(x*(x + 1)^2)^(1/3)

Detail solution

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

$\frac{x \left(2 x + 2\right) + \left(x + 1\right)^{2}}{3 x^{\frac{2}{3}} \left|{x + 1}\right|^{\frac{4}{3}}}$
Now simplify:

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

The answer is:

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