Application +4 | -1

A_1, A_2

be two A.M.'s and

G_1, G_2

be two G.M.'s between

a

and

b

, then

\frac{A_1+A_2}{G_1 G_2}

is equal to

View answer and explanation

Correct option: C

\frac{a+b}{a b}

Option C (

\frac{a+b}{ab}

) is correct because, after calculating A1+A2 and G1G2, their ratio simplifies to (a+b)/ab.
