x+98=37698lllllllaaaaaa
x+x=98 x可以是?
x+3x-(9x+30x)=98
(5x-2)*(x+8)=5x*x+98
(98-X)+(100-X)+X=X/0.
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
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
x^3+x^2+x+1=0,则x^97+x^98+x^99+.x^103=
(X+X)+(X-X)+(X*X)+(X/X)=100
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+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的值见上
f(x)=[1+x+x^2+x^3+...+x^47]/[1+x+x^2+x^3+...+x^98],求f'(-1)
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
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
(98+11x)/(x+16)=8 x=?
