log(1 + 2*x) ------------ log(10)
log(1 + 2*x)/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 the constant is zero.
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:
So, the result is:
The answer is:
2 ----------------- (1 + 2*x)*log(10)
