(X+X)+(X-X)+(X*X)+(X/X)=100
x+x=x+15
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
x/x平方-x+2=2x/x+1
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
先化简,再求值:(x-2/x-x+2/x)/x-2/4x,x=2011
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
