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

    1. Let u=x6u = x^{6}.

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

    3. Then, apply the chain rule. Multiply by ddxx6\frac{d}{d x} x^{6}:

      1. Apply the power rule: x6x^{6} goes to 6x56 x^{5}

      The result of the chain rule is:

      6x7- \frac{6}{x^{7}}

    So, the result is: 24x7- \frac{24}{x^{7}}


The answer is:

24x7- \frac{24}{x^{7}}
