Question

What is the product of (√5 + √2) and (√5 - √2)​

Answer 1

Answer:

3

Step-by-step explanation:

(a+b)(a-b) = a²-b²

(√5 + √2)(√5 - √2) = 5-2 = 3

Answer 2

$(a + b)(a - b) = {a}^{2} - {b}^{2}$

$( \sqrt{5} + \sqrt{2} )( \sqrt{5} - \sqrt{2} ) = { \sqrt{5} }^{2} - { \sqrt{2} }^{2} \\ = 5 - 2 \\ = 3$

Hope this will help....
