a: \(\dfrac{-13}{40}< \dfrac{-12}{40}\)
\(\dfrac{-5}{6}>\dfrac{-91}{104}\)
![](https://rs.olm.vn/images/avt/0.png?1311)
a) 0,(26) = 0,262626...
Vì 0,262626... > 0,261 => 0,(26) > 0.261
b) 0,14(9) = 0,149999...
Vì 0,149999... < 0,15 => 0,14(9) < 0,15

Ta có : \((0,5)^{201}>(0,5)^{200}=(0,5)^{2\cdot100}=(0,5^2)^{100}=(0,25)^{100}\)
Ta thấy : \((0,25)^{100}< (0,3)^{100}\)
\(\Rightarrow(0,3)^{100}>(0,5)^{201}\)
