Binomial theorem - Wikipedia

WebLet P be a polynomial with integer coefficients and degree at least two. We prove an upper bound on the number of integer solutions n ≤ N to n! = P (x) which yields a power saving over the trivial bound. In particular, this applies to a century-old problem of Brocard and Ramanujan. The previous best result was that the number of solutions is o (N).The proof … WebA power of two is a number of the form 2 n where n is an ... = 4 × 5 k−1 (see Multiplicative group of integers modulo n).
