计算:(1-2)x(2一3)x(3-4)x……x(100-101)
如何计算 (x+1)(x+2)(x+3)(x+4)
计算(X-1)(X-2)(X-3)(X-4)
1x+2x+3x+4x+5x+6x+7x…+99x=100
计算1/(x+1)(x+2)+1/(x+2)(x+3)+1/(x+3)(x+4)+……+1/(x+2007)(x+200
计算:(x-1)(x^2-4X+3)-x(x^2-5X+2)有过程
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
计算2x X 4x--3x=
计算 x(x+3)-(x-1)(x-2)
计算:(x+1)(x-2)(x-3)(x-6)
请直接用(2)中的规律计算1/(X-1)(X-2)+1/(X-2)(X-3)+1/(X-3)(X-4)+…+1/(X-9
计算1/x-1 1/(x-1)(x-2) 1/(x-2)(x-3)… 1/(x-99)(x-100)及规律是什么
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
