Let a be the A.M. and b,c bet wo G.M\'s between two positive numbers. Then `b^3+c^3` is equal to (A) `abc` (B) `2abc` (C) `3abc` (D) `4abc`

Let alpha be the A.M. and beta , gamma be two G.M.\'s between two positive numbes then the value of (beta^3+gamma^3)/(alphabetagamma) is (A) 1 (B) 2 (C) 0 (D) 3

If a be the arithmetic mean and b, c be the two geometric means between any two positive numbers, then (b^3 + c^3) / abc equals

Let a,b,c be positive numbers,then the minimum value of (a^(4)+b^(4)+c^(2))/(abc)

If a*b=b*c=c*a=0," then [abc] is equal to

If a,b,c are positive real numbers,then sqrt(a^(-1)b)x sqrt(b^(-1)c)x sqrt(c^(-1)a) is equal to: 1 (b) abc(c)sqrt(abc)(d)(1)/(abc)

In a Delta ABC, If a is the arithmetic mean and b,c(b!=c) are the geometric means between any two positive real number then (sin^(3)B+sin^(3)C)/(sin A sin B sin C)=
