Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = x$ and $g{\left(x \right)} = e^{\frac{1}{x^{3}}}$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Apply the power rule: $x$ goes to $1$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = \frac{1}{x^{3}}$ .
2. The derivative of $e^{u}$ is itself.
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{1}{x^{3}}$ :
  1. Let $u = x^{3}$ .
  2. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} x^{3}$ :
    1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
    The result of the chain rule is:
    
    $- \frac{3}{x^{4}}$
  The result of the chain rule is:
  
  $- \frac{3 e^{\frac{1}{x^{3}}}}{x^{4}}$
Now plug in to the quotient rule:

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

$\frac{\left(x^{3} + 3\right) e^{- \frac{1}{x^{3}}}}{x^{3}}$

The answer is:

$\frac{\left(x^{3} + 3\right) e^{- \frac{1}{x^{3}}}}{x^{3}}$
