__________ / 2 \/ x + 3*x
/ __________\ d | / 2 | --\\/ x + 3*x / 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 a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
3/2 + x ------------- __________ / 2 \/ x + 3*x
2 (3 + 2*x) 1 - ----------- 4*x*(3 + x) --------------- ___________ \/ x*(3 + x)
/ 2\ | (3 + 2*x) | 3*|-4 + ----------|*(3 + 2*x) \ x*(3 + x) / ----------------------------- 3/2 8*(x*(3 + x))
