The problem is, Wolfram Alpha is calculating the limit in the complex plane with the definition I first gave, but by what I understood the limit that was asked ignores this and uses only the fact negative numbers have odd roots (ie. we want the limit of a sequence, not the limit of the function)
Actually, the domain of isn't specified, so I'm a little confused as well. It's actually a question from Wade's Introduction to Analysis (4th Ed), and the answer given is 1. It does seem that it's the sequence it's referring to, then?

I don't know. If the book says the solution is 1 then it can't be the sequence since that one converges to -1, but otherwise it wouldn't make sense writing x ->0+. I'm confused.
