Answer 2

Answer: (7 - 2√10) / 3

Step-by-step explanation:

√5 - √2

--------------

√5 + √2

=> multiply it by √5 - √2 / √5 - √2 in order to rationalize

=> √5 - √2 / √5 + √2 *  √5 - √2 / √5 - √2

=> (√5 - √2)² / √5² - √2²

=> [√5² + √2² - 2*√5*√2] / 5 - 2

=> 5 + 2 - 2√10  /  3

=> (7 - 2√10) / 3

=> 7 - 2√10
