Web9 okt. 2013 · Then the other n-k elements automatically go to B. So for each k this number is just ${n \choose k}$. Now, we add this for all k reviously mentioned to get $\sum_{k = 0}^n {n \choose k}$ And thus, $2^n = \sum_{k = 0}^n {n \choose k}$ Share. Cite. Follow answered Sep 17, 2024 at 22:12. Francisco ...

If n is a square, all the exponents are even, so the number of factors is a product of odd numbers and so is odd. If n is not a square, then at least one exponent is odd, so the number of factors has an even integer divisor and is even. chai versus coffee
