Question

parentheses:
(6−3–√)(3+3–√)

= 6(3) + 6(3) - 6√3 - 3(3) - 3(3) + 3√3 – √(3)(3) – √(3)(3)

= 18 + 18 - 6√3 - 9 - 9 + 3√3 – 3√3 – 3√3

= (18 + 18 - 9 - 9) + (-6√3 + 3√3 - 3√3 - 3√3)

= 36 - 18√3 - 12√3

= 36 - 30√3

Therefore, (6−3–√)(3+3–√) simplifies to 36 - 30√3.

Answer 1

Note: The original equation is not clear because it is missing an operator between the terms (√) and (3). Assuming that is a multiplication instead of an addition, the simplification provided is correct.
