A = \(\left(1\dfrac{4}{a^2}\right)\left(1\dfrac{4}{b^2}\right)\)
= \(\dfrac{\left(a2\right)\left(a+2\right)\left(b2\right)\left(b+2\right)}{a^2b^2}\)
= \(\dfrac{ab\left(a+2\right)\left(b+2\right)}{a^2b^2}\)
= \(\dfrac{ab+2\left(a+b\right)+4}{ab}\)
= \(1+\dfrac{8}{ab}\)
\(\le1+\dfrac{8}{\left(\dfrac{a+b}{2}\right)^2}=1+8=9\)

A= (12a)(12b)(1+2a)(1+2b
)
A= ( 1a+ba
)(1a+bb)(1+a+ba)(1+a+bb
)
A= ba
.ab.(2+ba)(2+ab
)
A= 4 +1 + 2 (ba+ab
) >= 5 +2. 2√ba.ab= 5+4 =9
