________ / 2 \/ x + 5
/ ________\ d | / 2 | --\\/ x + 5 / dx
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:
2 x 1 - ------ 2 5 + x ----------- ________ / 2 \/ 5 + x
/ 2 \ | x | 3*x*|-1 + ------| | 2| \ 5 + x / ----------------- 3/2 / 2\ \5 + x /
