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:

If A_(1),A_(2) be two A.M.and G_(1),G_(2) be two G.M.s between aandb then (A_(1)+A_(2))/(G_(1)G_(2)) is equal to (a+b)/(2ab) b.(2ab)/(a+b) c.(a+b)/(ab) d.(a+b)/(sqrt(ab))

If A_(1),A_(2) be two A.M.'s and G_(1),G_(2) be two G.M.,s between a and b, then (A_(1)+A_(2))/(G_(1)G_(2)) is equal to

If a be one A.M and G_(1) and G_(2) be then geometric means between b and c then G_(1)^(3)+G_(2)^(3)=

If G_(1) . G_(2) , g_(3) are three geometric means between two positive numbers a and b , then g_(1) g_(3) is equal to

If A_(1),A_(2),G_(1),G_(2) and H_(1),H_(2) be two AMs,GMs and HMs between two quantities then the value of (G_(1)G_(2))/(H_(1)H_(2)) is

Let 3 geometric means G_(1),G_(2),G_(3) are inserted between two positive number a and b such that (G_(3)-G_(2))/(G_(2)-G_(1))=2 then (b)/(a) equal to (i)2 (ii) 4 (iii) 8 (iv) 16

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

If A_(1) and A_(2) are two A.M.s between a and b and G_(1) and G_(2) are two G.M.s between the same numbers then what is the value of (A_(1)+A_(2))/(G_(1)G_(2))
