Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
1 ------------ 2/3 3*(x + 1)
-2 ------------ 5/3 9*(1 + x)
10 ------------- 8/3 27*(1 + x)
