This might be a silly question and an obvious one, it's something I just wanted confirmation/clarification on. I've been recently reading a lot of mathematical papers/journals from around the world and have noticed something in particular. A lot of formulas or things they are postulating use raised powers. For example 10^7 which of course is the same as 10000000. Now is this just for connivence sake? couldn't they just use 10000000 instead? Or is there some property held within writing things in raised form?
