I just want to simplify this. LOL. I don't mean this either:

I think it's this:

It looks retarded though. Is this right? I checked it using my calculator and I get the right answer but it looks weird. They have different bases and different exponents so there nothing more you can do with them.

Let's say the 3 was a 2:

So:

Is that right?

Hi;

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
