So you have n to the k in the numerator and you have n to the k in the denominator. So the highest degrees are the same, the coefficients are 1. So this limit is 1. Another way you could do it, you could divide the numerator and the denominator by n to the k and you would get, this would be 1 plus 1 over n plus 1 over everything else would have a 1 over n in it. And this would just be a 1. And if you take the limit as you approach infinity, then all of these other terms would be 0 and you'd get left with 1 over 1. But either way, you have the same degree in the top and the bottom and their coefficients are the same.
