Correct Option: B
| x = √3 − | |
| √3 |
| y = √3 + | |
| √3 |
| x + y = √3 − | + √3 + | = 2√3 | ||
| √3 | √3 |
| xy = | ![]() | √3 − | ![]() | ![]() | √3 + | ![]() | ||
| √3 | √3 |
| = 3 – | = | = | |||
| 3 | 3 | 3 |
| ∴ | + | = | |||
| y | x | xy |
| = | |
| xy |
| = | (2√3)3 − 3 × | (2√3) | |||
| 3 | |||||
