Question

So sánh:

         \(\sqrt{2}+\sqrt{4}\) và \(\sqrt{3}+5\)

Answer 1

Ta có:

\(\sqrt{3}>\sqrt{2}\left(3>2\right).\)

\(5>\sqrt{5}>\sqrt{4}\)

\(\Rightarrow\sqrt{2}+\sqrt{4}< \sqrt{3}+5\)

Answer 2

\(\sqrt{2}+\sqrt{4}< \sqrt{3}+5\)

Answer 3

\(\sqrt{2}+\sqrt{4}=1.41+2\)\(2\)\(=3.41\)

\(\sqrt{3}+5=1.73+5\)\(=6.73\)

\(=>\sqrt{2}+\sqrt{4}< \sqrt{3}+5\)
