实数x、y、z满足x+y+z+8=2√(x-1)+4√(y-2)+6√(z-3),求x+y+z的值是多少?

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 已知实数x y z满足x/(x+1)=y/(y+2)=z/(z+3)=(x+y+z)/3,求x+y+z的值 已知实数x y z满足x/(x+1)=y/(y+2)=z/(z+3)=(x+y+z)/3,求x+y+z的值 已知实数x,y,z满足2｜x-y｜+√2y+z+z2-z+1/4=0求x+y+z的值 已知实数x,y,z,满足那么x+y=6,z^2=xy-9,求(x+y)^z 已知实数xyz满足|x-2y|+2√(2y+z)+z-2z+1=0,求x+y+z的值 实数x、y、z满足x+y+z+8=2√(x-1)+4√(y-2)+6√(z-3),求x+y+z的值是多少? 若实数x,y,z满足x+y+z=4[√(x-5)+√(y-4)+√(z-3)]求x,y,z的值 已知实数x,y,z满足x+y+z=2根号x-1+2根号y-1+2根号z-1求X+2Y+3Z 已知实数x,y,z满足关系式2x-3y-z=0,x-2y+z=0,求x比y比z的值 已知x,y,z均为实数,且满足:x+2y-z=6,x-y+2z=3.求x+y+z的最小值 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 实数x,y,z满足（x-z)的平方减4（x-y)（y-z）=0求证z+x-2y=0 已知实数 x y z 满足x+y-z=0 ,3x-y+2z=0 则x :y :z 已知三个实数x,y,z满足条件(z-x)^2-4(x-y)(y-z)=0,求证:x,y,z成等差数列 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/y+z+y/z+x+z/x+y=1求x^2/y+z+y^2/z+x+z^2/x+y的值 纠正下！：已知实数xyz满足（x/y+z）+（y/z+x）+（z/x+y）=1求（x^2/y+z）+（y^2/z+x）+（z^2/x+y）的值 设正实数x,y,z满足x+2y+z=1,则1/(x+y)+9(x+y)/(y+z)的最小值
