2 4*log (x)
d / 2 \ --\4*log (x)/ dx
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 :
The derivative of is .
The result of the chain rule is:
So, the result is:
The answer is:
-8*(-1 + log(x)) ---------------- 2 x
8*(-3 + 2*log(x)) ----------------- 3 x
