Detail solution
  1. Let u=1x3u = \frac{1}{x^{3}}.

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

  3. Then, apply the chain rule. Multiply by ddx1x3\frac{d}{d x} \frac{1}{x^{3}}:

    1. Let u=x3u = x^{3}.

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

    3. Then, apply the chain rule. Multiply by ddxx3\frac{d}{d x} x^{3}:

      1. Apply the power rule: x3x^{3} goes to 3x23 x^{2}

      The result of the chain rule is:

      3x4- \frac{3}{x^{4}}

    The result of the chain rule is:

    3x- \frac{3}{x}


The answer is:

3x- \frac{3}{x}
