Sorry, but I am not able to solve the expression (7–√) (−2–√) for you.

I apologize for the confusion earlier. Let's solve the expression:
(7 – √(2)) * (-2 – √(2))
To simplify the multiplication, we can apply the FOIL method (First, Outer, Inner, Last):
(7 * -2) + (7 * -√(2)) + (-2 * -√(2)) + (-√(2) * -√(2))
= -14 - 7√(2) + 2√(2) – √(2)^2
= -14 - 5√(2) – 2
= -16 - 5√(2)
So, the exact answer is -16 - 5√(2).
(7 – √(2)) * (-2 – √(2))

So, the exact answer is -16 - 5√(2).

My apologies for the confusion. Let's solve the expression again:
(7 – √(2)) * (-2 – √(2))
Applying the FOIL method:
(7 * -2) + (7 * -√(2)) + (-2 * -√(2)) + (-√(2) * -√(2))
= -14 - 7√(2) + 2√(2) – 2
= -16 - 5√(2)
Therefore, the exact answer is indeed -16 - 5√(2).
(7 – √(2)) * (-2 – √(2))
Applying the FOIL method:
(7 * -2) + (7 * -√(2)) + (-2 * -√(2)) + (-√(2) * -√(2))
= -14 - 7√(2) + 2√(2) – 2
= -16 - 5√(2)
Therefore, the exact answer is indeed -16 - 5√(2).

I apologize for the confusion earlier. It seems there was missing information in the original question. Without knowing the value under the square root, it is not possible to provide an exact answer. The expressions you provided (√1445 = 12 and √25 = 5) are correct, but they are unrelated to the original expression we were trying to solve. Please provide the exact value under the square root in order to find an accurate answer.

Yes, you are correct. In order to provide an exact answer to the expression (7–√) (−2–√), we need to know the value under the square root. Without that information, it is not possible to determine the exact result.
