Answer 1

$\color{blue}{ANSWER}$

(√2 - √3)(√2 + √3)

by using the identity of (a-b)(a+b) = a² - b² we get,

=> (√2)² - (√3)²

=> 2-3

=> -1

Hence, option (a) A rational number is your answer

Answer 2

Answer:

$( \sqrt{2} - \sqrt{3})( \sqrt{2} + \sqrt{3} )$

Step-by-step explanation:

here by using the formula

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

${( \sqrt{2}) }^{2} - { (\sqrt{3} )}^{2}$

2-3
