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

(x*x^(1/3))*sin(1/x)

Detail solution

Apply the product rule:

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

$f{\left(x \right)} = \sqrt[3]{x} x$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
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 $1$
  $g{\left(x \right)} = \sqrt[3]{x}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Apply the power rule: $\sqrt[3]{x}$ goes to $\frac{1}{3 x^{\frac{2}{3}}}$
  The result is: $\frac{4 \sqrt[3]{x}}{3}$
$g{\left(x \right)} = \sin{\left(\frac{1}{x} \right)}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = \frac{1}{x}$ .
2. The derivative of sine is cosine:
  
  $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{1}{x}$ :
  1. Apply the power rule: $\frac{1}{x}$ goes to $- \frac{1}{x^{2}}$
  The result of the chain rule is:
  
  $- \frac{\cos{\left(\frac{1}{x} \right)}}{x^{2}}$
The result is: $\frac{4 \sqrt[3]{x} \sin{\left(\frac{1}{x} \right)}}{3} - \frac{\cos{\left(\frac{1}{x} \right)}}{x^{\frac{2}{3}}}$
Now simplify:

$\frac{\frac{4 x \sin{\left(\frac{1}{x} \right)}}{3} - \cos{\left(\frac{1}{x} \right)}}{x^{\frac{2}{3}}}$

The answer is:

$\frac{\frac{4 x \sin{\left(\frac{1}{x} \right)}}{3} - \cos{\left(\frac{1}{x} \right)}}{x^{\frac{2}{3}}}$
