log(2*x + 3) ------------ log(3)
d /log(2*x + 3)\ --|------------| dx\ log(3) /
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
The derivative of is .
Then, apply the chain rule. Multiply by :
Differentiate term by term:
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 derivative of the constant is zero.
The result is:
The result of the chain rule is:
So, the result is:
Now simplify:
The answer is:
2 ---------------- (2*x + 3)*log(3)
-4 ----------------- 2 (3 + 2*x) *log(3)
16 ----------------- 3 (3 + 2*x) *log(3)
