Answer:16√5 + 5√15 + 9 / 88

Step-by-step explanation:

2+√3 / 5√5 - 3√3

2 +√3 / 5√5 - 3√3 * 5√5 + 3√3 / 5√5 + 3√3     (conjugate of  5√5 - 3√3)

(2 + √3 ) * (5√5 + 3√3) / (5√5 - 3√3) * (5√5 + 3√3)

(2 * 5√5)+(2 * 3√3)+(√3 * 5√5)+(√3 * 3√3) / (5√5)² - (3√3)²  (a-b)(a+b)=a²-b²

10√5 + 6√5 + 5√15 + 3√9 / (25 * 5) - (9 * 3)

16√5 + 5√15 + 3*3 / 125-27

16√5 + 5√15 + 9 / 125-27

16√5 + 5√15 + 9 / 88

∴ 88 is a raitonal no.
