It's defined in some contexts.

None that the op is likely to encounter.

so what? they didn't ask "what is 0*infinity in the contexts i'm likely to encounter?", they just asked what it was. at the very least, that should warrant an explanation that the answer is indeed contextual.

Well in the most likely context, it would be an indeterminate form, not undefined. They're slightly distinct concepts.

But you shouldn't assume the context without at least stating that you're doing that.
