If `x, y, z, t > 0` and `xyzt = 81` then minimum value of `x + 2y + 7 + 8t` is

If x,y,z , t gt 0 and xyzt=81 then minimum value of x+2y+z+8t is

If x > 0, y > 0, z>0 and x + y + z = 1 then the minimum value of x/(2-x)+y/(2-y)+z/(2-z) is:

If x > 0, y > 0, z>0 and x + y + z = 1 then the minimum value of x/(2-x)+y/(2-y)+z/(2-z) is:

If x > 0, y > 0, z>0 and x + y + z = 1 then the minimum value of x/(2-x)+y/(2-y)+z/(2-z) is

If x > 0, y > 0, z>0 and x + y + z = 1 then the minimum value of x/(2-x)+y/(2-y)+z/(2-z) is: a. 0.2 b. 0.4 c. 0.6 d. 0.8

If x>0,y>0,z>0 and x+y+z=1 then the minimum value of (x)/(2-x)+(y)/(2-y)+(z)/(2-z) is

If xyz = 1 and x, y, z gt 0 then the minimum value of the expression (x+2y)(y+2z)(z+2x) is

If xyz = 1 and x, y, z gt 0 then the minimum value of the expression (x+2y)(y+2z)(z+2x) is

If x + y + z =a and the minimum value of a/x+a/y+a/z is 81^lambda , then the value of . lambda is

If x + y + z =a and the minimum value of a/x+a/y+a/z is 81^lambda , then the value of . lambda is
