Question 4708: Hello, I would appreciate it if one of the experts could take a look at the following two problems and let me know if my answer is correct:

Problem 1:
Find: lne^5 - lne^4
My answer: 1

Problem 2:
The point (3, 64) lies on the graph of the exponential function y = b^x. Find the base, b, of this exponential function.
My answer: b = 4

I also need assistance with the following question:

What is the inverse of the function f(x)=log8x ?
**8 is the base of the log

In advance, thanks so much for your assistance! :~)

You can put this solution on YOUR website!
1. correct
2. correct
3. y = log-base8 (x)

so, 8%5Ey+=+x. So the inverse function is f%5E%28-1%29%28x%29+=+8%5Ex
