1 -- 5 x
1/(x^5)
Let u=x5u = x^{5}u=x5.
Apply the power rule: 1u\frac{1}{u}u1 goes to −1u2- \frac{1}{u^{2}}−u21
Then, apply the chain rule. Multiply by ddxx5\frac{d}{d x} x^{5}dxdx5:
Apply the power rule: x5x^{5}x5 goes to 5x45 x^{4}5x4
The result of the chain rule is:
The answer is:
-5 ---- 5 x*x
30 -- 7 x
-210 ----- 8 x
