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.
