solving an exponential as a variable

Hi,

I have a simple question; 10^x= 10000 . I know the answer is x=4, but what I want to know is how do I find the value of x algebraically. I looked on some websites, and they suggested finding the log or what but I havn't done logs yet.

Technically the logarithms are redundant though, since it can be seen from inspection that .
