Answer 1

Answer:

Hey mate your answer is here

Step-by-step explanation:

= 4 + 3√5 / 4 - 3√5

= 4 + 3√5 / 4 - 3√5 × 4 + 3√5 / 4 + 3√5

= [ (4)² + 2 (4) (3√5) + (3√5)² ] / (4)² - (3√5)²

= ( 16 + 45 + 24√5 ) / 16 - 45

= ( 61 + 24√5 ) / - 29

=  - 61 / 29 -24 / 29 × √5

∴a = - 61/29  and b = - 24 / 29
