If three positive real numbers a,b,c are in AP such that abc=4, then the minimum value of b is

If three positive real numbers a,b,c are in A.P.sich that abc=4, then the minimum value of b is a..2^(1/3) b.2^(2) c.2^(1/2) d.2^(3/23)

If three positive real numbers a,b,c are in AP with abc=64, then minimum value of b is:

in three positive numbers a, b and c are in A.P. such that abc = 8, then the minimum possible value of b is

If a and b are positive real numbers such that a+b =c, then the minimum value of ((4 )/(a)+ (1)/(b)) is equal to :

If a and b are positive real numbers such that a+b=6, then the minimum value of ((4)/(a)+(1)/(b)) is equal to

If the product of three positive real numbers say a,b,c be 27, then the minimum value of ab+bc+ca is equal to

If a,b,c are positive real numbers such that a+b+c=1 , then find the minimum value of (1)/(ab)+(1)/(bc)+(1)/(ac) .
