1/X(X+1)+1/(X+1)(X+2)+1/(X+2)(X+3).+1/(X+99)(X+100)=
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
1x+2x+3x+4x+5x+6x+7x…+99x=100
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
设函数f(x)=(x-1)(x-2)...(x-100)(x>100),求F'(X)
f(x)=x(x-1)(x-2)…(x-99)(x-100),求f'(100)
x(x-1)(x-2)...(x-99)(x-100)
x/x平方-x+2=2x/x+1
(X+1)X(X+2)X(X+3)=504
一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
