log(3*x + 1) ------------ log(10)
d /log(3*x + 1)\ --|------------| dx\ log(10) /
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:
3 ----------------- (3*x + 1)*log(10)
-9 ------------------ 2 (1 + 3*x) *log(10)
54 ------------------ 3 (1 + 3*x) *log(10)
