Answer 1

A) 2

Explanation:

We already know that
`i` equals -1, so we can substitute that into the expression.

`(√(3) +(-1))(√(3) -(-1))\\(√(3) -1)(√(3)+1)`

Now we can use the distributive property to solve the rest

`(√(3) -1)(√(3)+1)\\√(3) *√(3) +√(3) -√(3)-1\\ 3+0-1\\=2`

Hope this helps! I apologize if I get this incorrect.
