# Converting a log equation to exponential equation

## Homework Statement

the question asks to graph the equation:
(don't know how to use latex sorry)
f(x) = log5 (x) + 3 where the 5 is the base
Just for my curiosity what would the exponential equation be?
I can graph it, just can't get the exponential form
Tell me if this should go in the general math section.

You already put it in the general math section lol, look there for the working.
$$5^{f(x)} = 125x$$

Can that be expressed as x=? and can you show me how you did that?

"Solve" for x: y- 3= log5(x) so, using the definition of log5(x) as the inverse of 5x, x= 5y-3= (1/125)5y.
