\((\frac{3}{5})^2v/s(\frac{5}{3})^2\)
\((\frac{3}{5})^2=\frac{3}{5}.\frac{3}{5}=\frac{9}{25}\)
\((\frac{5}{3})^2=\frac{5}{3}.\frac{5}{3}=\frac{25}{9}\)
\(\frac{9}{25}v/s\frac{25}{9}=\frac{81}{225}v/s\frac{625}{225}\)
\(81< 625\left(625>81\right)\Rightarrow\frac{81}{225}< \frac{625}{225}\left(\frac{625}{225}>\frac{81}{225}\right)\)
\(\Rightarrow\left(\frac{3}{5}\right)^2< \left(\frac{5}{3}\right)^2\)và ngược lại
