(1+50%)x.0.7-x=10
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
(2x-2)(x-1)=0 x(x-5)=5x-10
(X-X*20%-18-(X-X*20%-18)*10%=X*1/2-3(过程)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
1)x+1/x=3,求x^10+x^5+1/x^5+1/x^10的值
计算:1/(x^2-7x+10)+1/(x^2-x-2)+1/(x^2+5x+4)+1/(x^2+11x+28)=( )
(x+1分之x+6)-(x^+3x+2分之3x^+10x+4)+(x+2分之2x+1)=0,解这个方程
(1)当x=2时,求代数式2x²(x²-x+1)-x(2x³-10x²+2x)的
30-3(3-X)=4X 3X+12*6=15X+12 4X-2(50-X)=20 12(X-13)=10(X+3) 1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
