Vietnamese students have fewer vacations than American ones
=>American students have longer vacations than Vietnamese ones.
Ta có :\(C=\frac{20^{10}+1}{20^{10}-1}\)
=> \(C-1=\frac{20^{10}+1-\left(20^{10}-1\right)}{20^{10}-1}=\frac{2}{20^{10}-1}\)
Lại có D = \(\frac{20^{10}-1}{20^{10}-3}\)
=> D - 1 = \(\frac{20^{10}-1-\left(20^{10}-3\right)}{20^{10}-3}=\frac{2}{20^{10}-3}\)
Vì \(20^{10}-1>20^{10}-3\Rightarrow\frac{2}{20^{10}-1}< \frac{2}{2^{10}-3}\Rightarrow C-1< D-1\Rightarrow C< D\)
Có : \(C=\frac{20^{10}+1}{20^{10}-1}\)
< = > \(C-1=\frac{20^{10}+1-\left(20^{10}-1\right)=\frac{2}{20^{10}-1}}{20^{10}-1}\)
có D \(\frac{20^{10}-1}{20^{10}-3}\)
=> D - 1 = \(\frac{20^{10}-1\left(20^{10}-3\right)}{20^{10}-3}=\frac{2}{20^{10}-3}\)
