(X+X)+(X-X)+(X*X)+(X/X)=100
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-22)+(x-24)+(x-27)+(x-20)=x
解一元一次方程 x/2+x/6+x/12+x/20+x/30+x/42=6
x/2+x/6+x/12+x/20+x/30+x/42=1
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
x+x=x+15
6x+19x=22.5 x+17%=9.36 78%x=39 70%x-18%x=3.12 12x+53=137 28%
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!)+.
int x=6; x += x -= x * x; printf("x = %d\n",x);
(x+2005)/ (x+2004)+(x+2007)/(x+2006)=(x+2008)/(x+2007)+(x+20
