in reply to 0**0

I thought that anything**0=1, even if it's 0**0, it's actually very logical.

Maybe engineers prefer 0**0=1, mathematicians prefer undef!

    It depends on where you're coming from. You're taking the limit of x**0 with x -> 0. But, take 0**x, which is zero for any value x > 0, thus when x -> 0... you end up with a different value for 0**0.

    That's why 0**0 is undefined. You can get different values for it, which are all valid in some way.
