If `x ,y ,a n dz` are posirive real umbers and `x=(12-y z)/(y+z)` . The maximum value of `x y z` equals.

If x,y,and z are positive real numbers and x=(12-yz)/(y+z) . The maximum value of (xyz) equals___________.

If x,y and z are positive real numbers such that x=(12-yz)/(y+z) the maximum value of xyz=

If x, y, z are positive real numbers such that x+y+z=a, then

If x,y,z are positive real numbers and x+y+z=1, then minimum value of ((4)/(x)+(9)/(y)+(16)/(z)) is

If x,y,z are positive real numbers such that y,z,x are in G.P. and x+y+z=xyz then the maximum value of equals (76)/(x^(4)+x^(2)+7) equals

Let x,y,z are positive real numbers satisfying x+y+z=1 . If the maximum value of x^(3)y^(2)z can be expressed as (a)/(b) where a and b are co-prime,then the value of (a+b) is

Let x,y,z are positive reals and x +y+z=60 and x gt 3. Maximum value of xyz is :

If x,yand z are positive real numbers,then the minimum value of (x)/(y)+(y)/(z)+(z)/(x) is:
