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`

If a be the A.M. and x, y be the two G.M's between b and c, show that x^3+y^3=2abc .

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

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

If a, b and c are three positive real numbers, then show that a^3 + b^3 + c^3 > 3abc .

If ’a' be the AM of b and c and p and q be the two G.M.,s between them, show that p^3+q^3=2abc .

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

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

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