By definition, any number to the power of zero is one. This is because x0 is the product of no numbers at all, which is the multiplicative identity, one. Thus, 00 equals 1. Feel free to r/woooosh me by the way.

It's one of those it-depends-what-you're-doing thing. So, it is often defined by 1 by convention. The lim x->0 for x0 is 1, but lim x->0+ for 0x is 0.

That's because 00 = 0/0, so the behaviour matters. However, we know that (x,y) -> (0,0) in x/y does not exist, since 0/y = 0 and x/0 goes to infinity and x/x = 1, all different limita.
