Answer 1

(√8-√2)(√8+√2)

by (a-b)(a+b) = a²-b²

= √8²-√2²

= 8-2

= 6

Answer 2

Answer:

6

Step-by-step explanation:

The given question is in the format of (a - b)(a + b).

(a - b)(a + b) = a² - b²

[∴ (a - b)(a + b) = a² - ab + ab - b² = a² - b²]

Here a = √8

b = √2

∴(√8 - √2)(√8 + √2) = (√8)² - (√2)²

⇒ 8 - 2

∴ 6 is the answer.
