Transform

Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Let $u = \sqrt[5]{x + \log{\left(x \right)}}$ .
2. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sqrt[5]{x + \log{\left(x \right)}}$ :
  1. Let $u = x + \log{\left(x \right)}$ .
  2. Apply the power rule: $\sqrt[5]{u}$ goes to $\frac{1}{5 u^{\frac{4}{5}}}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x + \log{\left(x \right)}\right)$ :
    1. Differentiate $x + \log{\left(x \right)}$ term by term:
      1. Apply the power rule: $x$ goes to $1$
      2. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
      The result is: $1 + \frac{1}{x}$
    The result of the chain rule is:
    
    $\frac{1 + \frac{1}{x}}{5 \left(x + \log{\left(x \right)}\right)^{\frac{4}{5}}}$
  The result of the chain rule is:
  
  $- \frac{1 + \frac{1}{x}}{5 \left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}$
So, the result is: $- \frac{1 + \frac{1}{x}}{\left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}$
Now simplify:

$- \frac{x + 1}{x \left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}$

The answer is:

$- \frac{x + 1}{x \left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}$
