$\dfrac{2^{16} – 2^{14}}{2^{18} – 2^{16}}$ $= \dfrac{2^{14}.(2^{2} – 1)}{2^{16}.(2^{2} – 1)}$ $= \dfrac{2^{14}}{2^{16}}$ $= \dfrac{1}{2^2}$ $= \dfrac{1}{4}$. Trả lời
`( 2^16 – 2^14 )/(2^18 – 2^16)`
`= ( 2^14 . 2^2 – 2^14 )/( 2^16 . 2^2 – 2 ^16 )`
`= ( 2^14 . ( 2^2 – 1 ) )/( 2^16 . ( 2^2 – 1 ) )`
`= 2^14/2^16`
`= 1/4`

$\dfrac{2^{16} – 2^{14}}{2^{18} – 2^{16}}$
$= \dfrac{2^{14}.(2^{2} – 1)}{2^{16}.(2^{2} – 1)}$
$= \dfrac{2^{14}}{2^{16}}$
$= \dfrac{1}{2^2}$
$= \dfrac{1}{4}$.
