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. Over, we have this n to the k, right? So we just, that's this part of it. Times the limit as, well actually, we don't have to worry, this is a constant.
