Answer 2

Answer: 3

Step-by-step explanation:

Since we know that on opening a determinant we multiply the left diagonal component and then subtract the product of right diagonal to it therefore on solving

(2-√3)(2+√3)-(3+√11)(3-√11)

[It forms (a^2-b^2=(a+b)(a-b) identity]

therefore=>(4-3)-(9-11)=1+2=(3)
