A. 5 / (2√5 + √3) . 2√5 - √3 / 2√5 - √3
= 10√5 - 5√3 / 4√25 - √9
= 10√5 - 5√3 / 4.5 - 3
= 10√5 - 5√3 / 17

b. 3√6 - √2 / (4√3 + √2) . 4√3 - √2 / 4√3 - √2
= (12√18 + 3√12 - 4√6 - √4) / 16√9 - √4
= (12√9.2 + 3√4.3 - 4√6 - 2) / 16.3 - 2
= 12.3√2 + 3.2√3 - 4√6 - 2 /48 - 2
= 36√2 + 6√3 - 4√6 - 2 / 46

c. 7√3 / (2√5-√2) . 2√5+√2 / 2√5+√2
= 14√15 + 7√6 / 4.5 - 2
