Question

`\sqrt{32}+\sqrt{50}+3\sqrt8-\sqrt{18}`

Answer 1

\(\sqrt{32}+\sqrt{50}+3\sqrt{8}-\sqrt{18}\)

\(=4\sqrt{2}+5\sqrt{2}+6\sqrt{2}-3\sqrt{2}\)

\(=\left(4+5+6-3\right)\sqrt{2}\)

\(=12\sqrt{2}\)

Answer 2

=4căn 2+5căn 2+6căn 2-3căn 2

=12căn 2

Answer 3

`\sqrt{32}+\sqrt{50}+3\sqrt8-\sqrt{18}`

`=\sqrt{4.8}+\sqrt{25.2}+3\sqrt8-\sqrt{9.2}`

`=2\sqrt8+5\sqrt2+3\sqrt8-3\sqrt2`

`=5\sqrt8+2\sqrt2`

`=\sqrt{5^(2).8}+2\sqrt2`

`=\sqrt{200}+2\sqrt2`

`=10\sqrt2+2\sqrt2`

`=12\sqrt2`
