`G_(1), S and G_(2)` are stages of

G_(1), S and G_(2) are phases noticeble in

G_1,(S ) and G-2 are sub-phases of ...................

If G_(1) and G_(2) are two geometric means and A is the arithmetic mean inserted two numbers,G_(1)^(2) then the value of (G_(1)^(2))/(G_(2))+(G_(2)^(2))/(G_(1)) is:

Interphase with definite events of G_(1) , S, G_(2) stages occur before the commencement of I. Mitosis II. Meiosis-I III. Meiosis-II IV. Binary fission of bacteria

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))

If A is the arithmatic mean and G_(1) and G_(2) be two geometric means between any two numbers then prove that, (G_(1)^(2))/(G_(2)) + (G_(2)^(2))/(G_(1))=2A

Two A.M.'s A_(1) and A_(2) , two G.M.'s G_(1) and G_(2) and two H.M.'s H_(1) and H_(2) are inserted between any two numbers , then H_(1)^(-1)+ H_(2)^(-1) equals :
