Question

(3-√7)(3+√7)= С решением!!!

Answer 1

Применяем формулу сокращенного умножения, разность квадратов т.е.
(а-в)(а+в) = а² -в²
(3-√7)(3+√7) = 3³ - (√7)² = 9-7=2

Answer 2

To find the product of (3 - √7) and (3 + √7), we can use the difference of squares formula, which states that (a - b)(a + b) = a^2 - b^2.

In this case, a = 3 and b = √7.

Let's calculate the result:

(3 - √7)(3 + √7) = 3^2 - (√7)^2 = 9 - 7 = 2

Therefore, the product of (3 - √7) and (3 + √7) is 2.
