How to do this question

Answer 1

`4√(3) -3√(2) (or) 2.68556`

Explanation:

first you're going to simplify the radical expression:

`-√(12)` becomes
`-2√(3)`

`√(18)` becomes
`3√(2)`

`2√(27)` becomes
`6√(3)`

your equation should now be
`-2√(3) -3√(2) +6√(3)`

next you're going to collect like terms
`-2√(3) +6√(3) =4√(3)`

so your final answer is
`4√(3) -3√(2)`
