98-(x-7.35)=18.22
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
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
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)(x+2)+1/(x+1)(x+2)(x+3).+1/(x+98)(x+99)(x+100)=?
138+x=3*(98-x)
若x³+x²+x+1=0,则y=x^97+x^98+...+x^103=?
方程(1X+2X+3X…+98X+99X+100X=50500X)请问X等于多少?
x+x=x+15
(x-1)(x的99次方+x的98次方+x的97次方+...+x+1)=?
