Exponential Function Question

In the exponential function a^x=b (a to the power x equals b), can I reduce this to x=? (what would x equal)?

The definition of the logarithm says that x equals the a-based logarithm of b,
x = log_a(b).
The result may be expressed also by using logarihms in any base:
x = log(b)/log(a).
