log(x - 2) ---------- log(4)
log(x - 2)/log(4)
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:
Apply the power rule: goes to
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:
1 -------------- (x - 2)*log(4)
-1 ---------------- 2 (-2 + x) *log(4)
