Webdifferentiate both sides to get ∑ n = 1 m n x n − 1 = m x m + 1 − ( m + 1) x m + 1 ( x − 1) 2 multiply by x on both sides to finally get ∑ n = 1 m n x n = m x m + 2 − ( m + 1) x m + 1 + x ( x − 1) 2 now let x = 2. This , then, yields: ∑ n = 1 m n 2 n = m 2 m + 2 − ( m + 1) 2 m + 1 + 2 Share Cite Follow answered Mar 9, 2024 at 16:36 WebThe following identity is known as Fermat's combinatorial identity: Give a combinatorial arguement (no computations are needed) to establish this identity.
