（X+X)+(X-X)+(X*X)+(X/X)=100
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
x-2x+3x-4x+5x.+99x-100x=25求解
2x+3x+4x+5x+x+6x+7x=100
已知x^4+x^3+x^3+x^2+x^1+1=0,求x^100+x^99+x^98+x^97+x^96的值
当x=2,求1/x＊(x+2)+1/(x+2)*(x++4)+1/(x+4)*(x+6)+.+1/(x+98)*(x+100)的值
当x=2,求1/x(x+2)+1/(x+2)*(x++4)+1/(x+4)*(x+6)+.+1/(x+98)*(x+100)的值
1/x(x+1)(x+2)+1/(x+1)(x+2)(x+3).+1/(x+98)(x+99)(x+100)=?
已知x^4+x^3+x^2+x^2+1=0,求x^100+x^99+x^98+x^97+x^96的值见上
已知x^4+x^3+x^2+x+1=0,求x^100+x^99+x^98+x^97+x^96的值.
已知x^4+x^3+x^2+x+1=0,求x^100+x^99+x^98+x^97+x^96的值
x^4+X^3+X^2+X^1+1=0求x^100+X^99+X^98+X^97+X^96的值
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+4x+5x+6x+7x…+99x=100
100(X - 2) + 10X + 2X = 100*2X + 10X + X - 2 - 495
100×2x+10x+3x+216=100×3x+10×2x+x
设函数f(x)=(x-1)(x-2)...(x-100)(x>100),求F'(X)
