n*n!
=(n+1-1)*n!
=(n+1)*n!-n!
=(n+1)!-n!
1*1!+2*2!+~~~~~~~~~+n*n!
=(2!-1!)+(3!-2!)+[(n+1)!-n!]
=(n+1)!-1
0么??
1( )2( )
2( )+1( )=1( )
(2+1)(2^2+1)(2^4+1)(2^6+1)(2^8+1)(2^10+1)......(2^2004+1)
1 1 1 2 1 1 2 1 1 1 1 1 2 2 1 下一行是什么?
-1 1 2 -2 2 ( )过程?
化简(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
(2+1)(2×2+1)(2×2×2×2+1)(2×2×2×22×2×2×2+10
(1-1/2^2)(1-1/3^2)....(1-1/10^2)
(1-1/2^2)(1-1/3^2)....(1-1/10^2)
(2+1)(2^2+1)(2^4+1)~~~~~~(2^32+1)+1
