1100=100/1+x+100/(1+x)^2+100/(1+x)^2
1+x+x^2+x^3+.+x^99+x^100
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
1x+2x+3x+4x+5x+6x+7x…+99x=100
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
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
1/x(x+1)(x+2)+1/(x+1)(x+2)(x+3).+1/(x+98)(x+99)(x+100)=?
已知x=100,求x(x+1)分之1+(x+1)(x+2)分之1+(x+2)(x+3)分之1+.+(x+99)(x+10
计算1/X(X+1)+1/(X+1)(X+2)+.+1/(X+99)(X+100)
x^4+X^3+X^2+X^1+1=0求x^100+X^99+X^98+X^97+X^96的值
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
【1】f[x]=x[x+1][x+2].[x+100]
设f(x)=x(x+1)(x+2).(x+100),则f '(0)=
