数学文字混杂 让我们尝试证明一个稍微复杂一些的等式：
∑ k = 0 n ( n k ) = 2 n \sum_{k=0}^{n} \binom{n}{k} = 2^n ∑ k = 0 n ( k n ) = 2 n
我们可以使用二项式定理证明这个等式。二项式定理表述为：
( a + b ) n = ∑ k = 0 n ( n k ) a n − k b k (a + b)^n = \sum_{k=0}^{n} \binom{n}{k} a^{n-k} b^k ( a + b ) n = ∑ k = 0 n ( k n ) a n − k b k
现在，令 a = 1 a = 1 a = 1 b = 1 b = 1 b = 1
( 1 + 1 ) n = ∑ k = 0 n ( n k ) 1 n − k 1 k (1 + 1)^n = \sum_{k=0}^{n} \binom{n}{k} 1^{n-k} 1^k ( 1 + 1 ) n = ∑ k = 0 n ( k n ) 1 n − k 1 k
2 n = ∑ k = 0 n ( n k ) 2^n = \sum_{k=0}^{n} \binom{n}{k} 2 n = ∑ k = 0 n ( k n )
这证明了 ∑ k = 0 n ( n k ) = 2 n \sum_{k=0}^{n} \binom{n}{k} = 2^n ∑ k = 0 n ( k n ) = 2 n
