Answer 1

6sqrt3 = sqrt(36*3) = sqrt108

so choice B is right sure

hope helped

Answer 2

The equivalent expression will be
`5i√(3)`

Explanation:

The given expression is:
`√(-108)-√(-3)`

`√(-108)-√(-3)\\ \\ =√(36*(-3))-√(-3)\\ \\ =√(36)*√(-3)-√(-3)\\ \\ =6√(-3)-√(-3)\\ \\ =5√(-3)\\ \\ =5i√(3)`

[As
`i= √(-1)`]

So, the equivalent expression will be
`5i√(3)`
