2/x^7

Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Let $u = x^{7}$ .
2. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} x^{7}$ :
  1. Apply the power rule: $x^{7}$ goes to $7 x^{6}$
  The result of the chain rule is:
  
  $- \frac{7}{x^{8}}$
So, the result is: $- \frac{14}{x^{8}}$

The answer is:

$- \frac{14}{x^{8}}$
