a/ \(\sqrt{10}< \sqrt{16}=4\)
b/ \(\sqrt{40}>\sqrt{36}=4\)
c/ \(\sqrt{15}+\sqrt{24}< \sqrt{16}+\sqrt{25}=4+5=9\)
d/ \(3\sqrt{2}=\sqrt{18}< \sqrt{20}=2\sqrt{5}\)
a) \(\sqrt{10}\)và 4
4 = \(\sqrt{16}\)
Do \(\sqrt{16}>\sqrt{10}\)nên \(4>\sqrt{10}\)
b) \(\sqrt{40}\)và 6
6 = \(\sqrt{36}\)
Do \(\sqrt{40}>\sqrt{36}\)nên\(\sqrt{40}>6\)
