若实数XYZ满足2|x-y|+√2y+z+z方-z+1//4=0 求X+Y+Z 2y+z在根号里

若实数XYZ满足2|x-y|+√2y+z+z方-z+1//4=0 求X+Y+Z 2y+z在根号里 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 已知实数xyz满足|x-2y|+2√(2y+z)+z-2z+1=0,求x+y+z的值 若实数xyz满足x=6-y,z^2=xy-9.求证x=y快 若实数x、y、z满足x^2+2y^2+z^2+5小于或等于2xy-2y+4z,求xyz的值 若实数x、y、z满足x^2+2y^2+z^2+5小于或等于2xy-2y+4z,求xyz的值 已知实数xyz满足x/(x+1)=y/(y+2)=z/(z+3)=(x+y+z)/3求x+y+z的值 正数XYZ满足(X+Y)(X+Z)=2则XYZ(X+Y+Z)最大值 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Y+Z=3X^2-4X+6 Y-Z=X^2-4X+4.试确定XYZ大小关系 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 实数xyz满足y+z=6-4x+3x^2,z-y=4-4x+x^2,比较xyz的大小 XYZ=X+Y+Z找两个实数x,y,满足xy=x+y再找三个大于等于2的正整数,满足x+y+z=xyz忘说了，x、y、z都要不相等 x+y+z+2=xyz,x,y,z.为正实数,证明：xyz(x-1)(y-1)(z-1) 若实数x,y,z满足条件√x+√y-1+√z-2=1/4(x+y+z+9),求xyz的值如果好的话我还会加分的 若实数XYZ满足方程组 XY除以（X+2Y）=1 YZ除以(Y+2Z）=2 ZX除以(Z+2X) 则有 xyz都是实数,满足x+2y-z=6,x-y+2z=3求x*2+y*2+z*2的最小值 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xyz满足条件:(√x)+(√y-1)+(√z-2)=1/4(x+y+z+9),则xyz等于
