Question

(\(\sqrt{8}+\sqrt{50}\)).\(\sqrt{2}\)

Answer 1

\(\left(\sqrt{8}+\sqrt{50}\right).\sqrt{2}=\left(2\sqrt{2}+5\sqrt{2}\right).\sqrt{2}=4+10=14\)

Answer 2

Ta có: \(\left(\sqrt{8}+\sqrt{50}\right)\cdot\sqrt{2}\)

\(=4+10=14\)

Answer 3

\(\left(\sqrt{8}+\sqrt{50}\right)\sqrt{2}=\left(2\sqrt{2}+5\sqrt{2}\right)\sqrt{2}=2.2+5.2=14\)

Answer 4

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

\(=7\sqrt{2}.\sqrt{2}\)

\(=14\)
