/ 2 \ log\x + 14*x + 305/ -------------------- + 9 log(4)
log(x^2 + 14*x + 305)/log(4) + 9
Differentiate term by term:
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:
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 derivative of the constant is zero.
The result is:
The result of the chain rule is:
So, the result is:
The derivative of the constant is zero.
The result is:
Now simplify:
The answer is:
14 + 2*x ------------------------ / 2 \ \x + 14*x + 305/*log(4)
