I have a relatively simple equation, but am not sure I'm going about it in the right way.

My assumption is that I need to get the bases equal. The only way I know how to do this is to raise them to equalizing powers, the only number that can do that is 0. (This is the part I'm unsure of.)

After that the problem is really simple. The bases can be nixed and equations solved.

But that makes no sense... Plugging that in gets an obviously wrong answer, so I return to the part I'm unsure of and am now here.
