We're doing it k times. So the largest degree term is going to be n to the k, right? It's going to be n to the k plus something times n to the k minus 1. It's going to be this big kind of binomial, this big polynomial, kth degree polynomial. And that's really all we need to know for this derivation. So it's going to be n to the k plus blah, blah, blah, blah, blah, blah, blah, a bunch of other stuff. This thing, when you multiply it out.
