To find an inverse:

Swap the x's and y's. Wherever you see an x, write y and wherever you see y, write x. This creates the inverse equation.
If possible solve the new equation for y

Let's see how this works on your equation.
1. Swap the x's and y's:

2. Solve for y, if possible.
To solve our equation for y we start by rewriting the equation in exponential form. (This gets y out the of the argument of the logarithm.)

At this point we get stuck. We cannot solve this for y. (At least not for a single-valued expression for y.) So the inverse of your original function is not a function. The inverse can be expressed with any of the following:
