I'm not dumb or anything, I just suck at Math. [Seriously, I'd have a 96 average if I didn't get 80 in Math. And the most simplistic things in Math [like imaginery numbers] are hard for me. Who the hell cares about them? THEY'RE IMAGINERY!

Anyways, here's the question.

"Write the given power of i, in simplest terms as 1,i,-1, or -i.
i to the 300th power = ? "

They are going through the same atmosphere on the way up as the way down, so why don't they get really hot on the way up as they get when they come down?
