请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
X.(X十1)x(X十2)x(x十3) =360
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,

解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
6x-360(x-1)=360(x-1)-0.5x
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,=x^2/x(x-2)+(2x-4)/x(x^2-4)-(x^2+6x)/x(x^2-4)=x^2/x(x-2)-(x+2)/x(x-2)=(x-2)(x+1)/x(x-2)=(x+1)/x
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
X(X-1)=X
x*(x+1)*(x+2)*(x+3)=360 x=?计算过程以及结果
1.用公式计算:COSX=1-X*X/2!X*X*X*X/4!-X*X*X*X*X*X/6!.直到最后一项的绝对
小数奥数网xx(x +1)x(x+ 2)x(x +3)=360怎样算?
x+[x+1/6x]+[x-1/6]=6
5x/x(1+x)=6/1+x
6/(x-1)-(x+2)/x(x-1)=0
