log(x + 1) ---------- log(5) 3
3^(log(x + 1)/log(5))
Let .
Then, apply the chain rule. Multiply by :
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:
The result of the chain rule is:
Now simplify:
The answer is:
log(x + 1) ---------- log(5) 3 *log(3) ------------------ (x + 1)*log(5)
log(1 + x)
----------
log(5) / log(3)\
3 *|-1 + ------|*log(3)
\ log(5)/

(1 + x) *log(5)
log(1 + x)
---------- / 2 \
log(5) | log (3) 3*log(3)|
3 *|2 + ------- - --------|*log(3)
| 2 log(5) |
\ log (5) /
