.If x=y=2z and xyz=256 then what is the value of x?

• If x=y=2z and xyz=256
  
  x*x*x/2 =256
  x^3=512
  x=8

• w=y=2z
  xyz=256
  (2z)(2z)z=256
  4z^3=256
  z^3=64=4*4*4
  z=4
  x=2z=2(4)=8

• x=y=2z, so y=x, z=x/2
  By putting these values in eqn
  x^3/2=256
  x^3=512
  x^3=8^3
  x=8

• 8
  xyz=256
  2z*2z*z=256
  4z^3=256
  z=4
  x=2z
  x=8
