x^3+9x^2+27x+27
化简(x^2+3x+9)/(x^3-27)+(6x)/(9x-x^2)-(x-1)/(6+2x)
求化简:(x^2+3x+9)/(x^2-27)+(6x)/(9x-x^2)-(x-1)/(6+2x)
x²+3x+9/(x²-27)+6x/(9x-x²)-(x-1)/(6+2x)
化简~(x²+3x+9/x²-27)+(6x/9x-x²)-(x-1/6+2x)
(x2+3x+9)/(x2-27)+(6x)/(9x-x2)-(x-1)/(6+2x)
化简:(x^2+3x+9)/(x^3-27)+6/(9-x^2)-(x-1)/(6+2x)

x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
已知3^x*9^2x*27^x=9^8,求x的值
化简 :(x²+3x+9)/(x²-27)+(6x)/(9x-x²)-(x-1)/(6+2
2x-3=5x-27+9x(方程) 3.2x+6.8=13.2(方程) 5x+24-2x=14x+
