Help meh with an explication

Answer 1

`(6)/(\sqrt 2)= 3\sqrt 2`

Explanation:

Given

`(6)/(\sqrt 2)`

Required

Rationalize

`(6)/(\sqrt 2)`

To do this, we simply multiply by
`(\sqrt 2)/(\sqrt 2)`

`(6)/(\sqrt 2) * (\sqrt 2)/(\sqrt 2)`

This gives:

`(6 * \sqrt 2)/(\sqrt 2 * \sqrt 2)`

`(6 \sqrt 2)/(2 )`

`3\sqrt 2`

Hence:

`(6)/(\sqrt 2)= 3\sqrt 2`
