若实数X.Y.Z满足Y+Z=3X^2-4X+6 Y-Z=X^2-4X+4确定XYZ大

若实数x,y,z满足条件√x+√y-1+√z-2=1/4(x+y+z+9),求xyz的值 已知有实数x,y,z满足x^2+4y^2+z^2-2x-12y+4z+14=0,求xyz的值. 若实数x,y,z满足x+y/1=4,y+z/1=1,z+x/1=3/7,则xyz的值为多少 已知方程组4x-y+3z=0 2x+y+6z=0且xyz不等于0,则x/y+y/z+z/x是多少 已知有理数x.y.z满足（x-z-2)^2+(3x-6y-7)^2=/3y+3z-4/=0求xyz=多少 已知有理数x,y,z满足条件：|x-z-2|+|3x-6y-7|+（3y+3z-4）^2=0,则xyz=? 已知有理数x,y,z满足(x-z-2)^2+(3x-6y-7)^2+|3y+3z-4|=0求xyz的值 已知有理数x,y,z满足(x-z-2)²+(3x-6y-7)+|3y+3z-4|=0,则xyz= 若实数x,y满足根号x+根号y-1+根号z-2=4分之1(x+y+z+9),求xyz的值 已知实数x,y,z满足:xyz不等于0,2x+3y-13z=0,x-2y+4z=0,求(x^2+y^2-z^2)/(xy 已知x,y,z属于R+(正实数）,且xyz(x+y+z)=4+2*根号下3,则(x+y)(y+z)的最小值是? 有实数x,y,z；已知x+y+z=2,xyz=4；求Z的取值区间
