[3n(n+1)+n(n+1)(2n+1)]/6+n(n+2)化简 [3n(n+1)+n(n+1)(2n+1)]/6+n(n+2)化简 化简n分之n-1+n分之n-2+n分之n-3+.+n分之1 化简n分之n-1+n分之n-2+n分之n-3+.+n分之1 f(x)=e^x-x 求证(1/n)^n+(2/n)^n+...+(n/n)^n 化简(n+1)(n+2)(n+3) n*【n+1】*【n+2】化简成什么? 2n/（n+1）n! n(n+1)(n+2)等于多少? n+(n-1)÷2×n 求化简 n(n+1)(n+2)什么意思 1^n+2^n+...+2013^n 当n为正偶数,求证n/(n-1)+n(n-2)/(n-1)(n-3)+...+n(n-2).2/(n-1)(n-3)...1=n 英语翻译这句子是The n(th) term of a number sequence is given by formula n2-1 n(th)是n的某一次方，n(2)是n的2次方
