Ta có:\(\dfrac{97^{10}}{100^{10}}=(\dfrac{97}{100})^{10}\)
và \(\dfrac{7}{10}=\dfrac{70}{100}\)
Vì \(\dfrac{97}{100}\)> \(\dfrac{70}{100}\)
\(\Rightarrow(\dfrac{97}{100})^{10}\)> \(\dfrac{7}{10}\)
\(\Rightarrow\dfrac{97^{10}}{100^{10}}\)> \(\dfrac{7}{10}\)
Vậy \(\dfrac{97^{10}}{100^{10}}\)> \(\dfrac{7}{10}\).
