Question

\(\sqrt{10+\sqrt{24}+\sqrt{40}+\sqrt{60}}\)

Answer 1

bye mình đi ngủ đây chúc bạn ngủ ngon. bài này dễ lắm. 

Answer 2

\(\sqrt{10+\sqrt{24}+\sqrt{40}+\sqrt{60}}\)

\(=\sqrt{10+2\sqrt{6}+2\sqrt{10}+2\sqrt{15}}\)

\(=\sqrt{\left(\sqrt{2}+\sqrt{5}+\sqrt{3}\right)^2}\)

\(=\sqrt{2}+\sqrt{3}+\sqrt{5}\)

Answer 3

\(\sqrt{10+\sqrt{24}+\sqrt{40}+\sqrt{60}}=\sqrt{10+2.\sqrt{6}+2.\sqrt{10}+2.\sqrt{15}}\)

\(=\sqrt{2+3+5+2.\sqrt{2.3}+2.\sqrt{2.5}+2.\sqrt{3.5}}\)

\(=\sqrt{\left(\sqrt{2}+\sqrt{3}+\sqrt{5}\right)^2}=\sqrt{2}+\sqrt{3}+\sqrt{5}\)
