If A and G be the AM and GM between two positive no.'s, then the numbers are `Apmsqrt(A^2-G^2)`

If A and G be the A .M and G.M between two positive numbers, then the numbers are

If A and G be A.M.and GM.,respectively between two positive numbers,prove that the numbers are A+-sqrt((A+G)(A-G))

If A and G are AM and GM respectively between two numbers,prove that numbere is A+-sqrt((A+G)(A-G))

If A_(1) ,be the A.M.and G_(1),G_(2) be two G.M.'s between two positive numbers then (G_(1)^(3)+G_(2)^(3))/(G_(1)G_(2)A_(1)) is equal to:

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
