9^×-10.3^(x-1)+1
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
如果3x*x-x=1那么9x*x*x*x+12x*x*x-3x*x-7x+2001等于多少
x*x+2x+x*x+10x+x*x+25+2x+x*x+1+1+16+x*x+4x*x+9-12x+16x*x+4-1
x+2/x^2-x-6 + 2x/x^3-3x - x+1/x^2-6x+9
(x+2/x^2-x-6)-(2x/x^2-3x)-(x+1/x^2-6x+9)

(x-1)(x-3)(x-5)(x-7)-9 因式分解
化简[(2X-3/X)-1]/(X平方-9/X)
化简:1/x(x+1)+1/(x+1)(x+2)+1/(x+2)(x+3)+...+1/(x+8)(x+9)
分式方程1/[x(x+1)]+1/[(x+1)(x+2)]+1/[(x+2)(x+3)]+...+1/[(x+9)(x+
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
初中数学解方程x/x-2+x-9/x-1等于x+1/x-1+x-8/x-6
