\frac{1}{x^{6}}

1/(x^6)

Detail solution

Let $u = x^{6}$ .
Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} x^{6}$ :
1. Apply the power rule: $x^{6}$ goes to $6 x^{5}$
The result of the chain rule is:

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

The answer is:

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