若x+y+z=6,xy+yz+zx=11,xyz=6,则x/yz+y/zx+z/xy=若x+y+z=6,xy+yz+zx=11,xyz=6,则x/yz+y/zx+z/xy=若x+y+z=6,xy+yz

若x+y+z=6,xy+yz+zx=11,xyz=6,则x/yz+y/zx+z/xy=
若x+y+z=6,xy+yz+zx=11,xyz=6,则x/yz+y/zx+z/xy=

若x+y+z=6,xy+yz+zx=11,xyz=6,则x/yz+y/zx+z/xy=
若x+y+z=6,
x^2+y^2+z^2+2xy+2yz+xz=36
xy+yz+zx=11
x^2+y^2+z^2+2*11=36
x^2+y^2+z^2=14
xyz=6
则x/yz+y/zx+z/xy
=(x^2+y^2+z^2)/xyz
=14/6
=7/3
