Answer 2

Solution :-

LHS -

(4 - √5)/(4 + √5) + (4 + √5)/(4 - √5) + 2/(5 + √3)

+ 2/(5 - √3)

=> (4 - √5)² + (4 + √5)² / (4 + √5)(4 - √5)

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

=> 2 {(4)² + (√5)² } / (4)² - (√5)² + { 2(10)/(5)²-(√3)²}

=> 2 { 16 + 5 } / (16 - 5) + 20/ (25 - 3)

=> 2(21) / 11 + 20/22

=> 42/11 + 10/11

=> 52/11 = RHS
