If `a,b,c>=0` such that a+b+c=6 ,then maximum possible value of abc

If the positive real numbers a, b and c are in Arithmetic Progression, such that abc = 4, then minimum possible 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+b+c=24 , then the maximum value of abc is :

If a,b,c in R - {0} and a^(2) = bc and a + b +c = abc then the least possible value of a^(2) is

" if " |{:(1,,1,,1),(a,,b,,c),(bc,,ca,,ab):}|=|{:(1,,1,,1),(a,,b,,c),(a^(3),,b^(3),,c^(3)):}| where a,b,c are distinct positive reals then the possible values of abc is // are

If abc =0 then find the value of [(x^a)^b]^c .

If there are three significant digits in 0.abc , then what are the possible values of a, b and c?
