Answer 1

For anyone who still needs the answer it’s 2 I just took the test

Answer 2

Answer: The required value of the radical is
`6\sqrt2.`

Step-by-step explanation: We are given to evaluate the following radical :

`R=3\sqrt 8.`

We will be using the following property of radicals :

For real numbers a and b, we have

`√(a* b)=\sqrt a* \sqrt b.`

So,

`R\\\\=3\sqrt 8\\\\=3√(4* 2)\\\\=3* \sqrt 4* \sqrt 2\\\\=3* 2* \sqrt 2\\\\=6\sqrt 2.`

Thus, the required value of the given radical is
`6\sqrt2.`
