Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Let u=x+log(x)5u = \sqrt[5]{x + \log{\left(x \right)}}.

    2. Apply the power rule: 1u\frac{1}{u} goes to 1u2- \frac{1}{u^{2}}

    3. Then, apply the chain rule. Multiply by ddxx+log(x)5\frac{d}{d x} \sqrt[5]{x + \log{\left(x \right)}}:

      1. Let u=x+log(x)u = x + \log{\left(x \right)}.

      2. Apply the power rule: u5\sqrt[5]{u} goes to 15u45\frac{1}{5 u^{\frac{4}{5}}}

      3. Then, apply the chain rule. Multiply by ddx(x+log(x))\frac{d}{d x} \left(x + \log{\left(x \right)}\right):

        1. Differentiate x+log(x)x + \log{\left(x \right)} term by term:

          1. Apply the power rule: xx goes to 11

          2. The derivative of log(x)\log{\left(x \right)} is 1x\frac{1}{x}.

          The result is: 1+1x1 + \frac{1}{x}

        The result of the chain rule is:

        1+1x5(x+log(x))45\frac{1 + \frac{1}{x}}{5 \left(x + \log{\left(x \right)}\right)^{\frac{4}{5}}}

      The result of the chain rule is:

      1+1x5(x+log(x))65- \frac{1 + \frac{1}{x}}{5 \left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}

    So, the result is: 1+1x(x+log(x))65- \frac{1 + \frac{1}{x}}{\left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}

  2. Now simplify:

    x+1x(x+log(x))65- \frac{x + 1}{x \left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}


The answer is:

x+1x(x+log(x))65- \frac{x + 1}{x \left(x + \log{\left(x \right)}\right)^{\frac{6}{5}}}
