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_1G_2)`

If A_1 and A_2 are two A.M.’s between a and b, prove that : A_1+A_2 =a+b .

If A_1 and A_2 are two AMs between a and b then (2A_1 -A_2) (2A_2 - A_1) =

If A_1 and A_2 are two A.M.’s between a and b, prove that : (2A_1-A_2)(2A_2-A_1) =ab .

If A_1 and A_2 be the two .Ms between two numbers 7 and 1/7 then (2A_1-A_2)(2A_2-A_1)=

If A_(1),A_(2) are two A.M.'s and G_(1),G_(2) be two G.M.'s between two positive numbers a and b, then (A_(1)+A_(2))/(G_(1)G_(2)) is equal to (i) (a+b)/(ab) (ii) (a+b)/2 (iii) (a+)/(a-b) (iv) None of these

If A_1,A_2 be two AM's and G_1,G_2 be the two GM's between two number a and b , then (A_1+A_2)/(G_1G_2) is equal to

If A be the A.M. of two given numbers and g_1 and g_2 be two G.M.'s between them,then show that- 2A=(g_1^2)/(g_2)+(g_2^2)/g_1 .

If g_1 , g_2 are two G.M's between two numbers a and b, then (g_1^2)/(g_2)+(g_2^2)/(g_1) is equal to:

If A_1,A_2,A_3, A_4 and A_5 are the five A.M.'s between 2 nd 8, then find the value of A_1+A_2+A_3+A_4+A_5
