1 --- 10 x
1/(x^10)
Let u=x10u = x^{10}u=x10.
Apply the power rule: 1u\frac{1}{u}u1 goes to −1u2- \frac{1}{u^{2}}−u21
Then, apply the chain rule. Multiply by ddxx10\frac{d}{d x} x^{10}dxdx10:
Apply the power rule: x10x^{10}x10 goes to 10x910 x^{9}10x9
The result of the chain rule is:
The answer is:
-10 ----- 10 x*x
110 --- 12 x
-1320 ------ 13 x
