Detail solution
  1. Let u=log(x)3u = \log{\left(x \right)}^{3}.

  2. Apply the power rule: u\sqrt{u} goes to 12u\frac{1}{2 \sqrt{u}}

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

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

    2. Apply the power rule: u3u^{3} goes to 3u23 u^{2}

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

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

      The result of the chain rule is:

      3log(x)2x\frac{3 \log{\left(x \right)}^{2}}{x}

    The result of the chain rule is:

    3log(x)22xlog(x)3\frac{3 \log{\left(x \right)}^{2}}{2 x \sqrt{\log{\left(x \right)}^{3}}}


The answer is:

3log(x)22xlog(x)3\frac{3 \log{\left(x \right)}^{2}}{2 x \sqrt{\log{\left(x \right)}^{3}}}
