10 10*x - log (x + 10)
10*x - log(x + 10)^10
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 a constant times a function is the constant times the derivative of the function.
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Let .
The derivative of is .
Then, apply the chain rule. Multiply by :
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
The result of the chain rule is:
The result of the chain rule is:
So, the result is:
The result is:
Now simplify:
The answer is:
9
10*log (x + 10)
10 - ---------------
x + 10
8
10*log (10 + x)*(-9 + log(10 + x))
----------------------------------
2
(10 + x)
7 / 2 \
10*log (10 + x)*\-72 - 2*log (10 + x) + 27*log(10 + x)/
-------------------------------------------------------
3
(10 + x)
