Answer 2

Answer:

Hence, (√5 + 1)/(√5 - 1) + (√5 - 1)/(√5 + 1) = 3

Step-by-step explanation:

Given, (√5 + 1)/(√5 - 1) + (√5 - 1)/(√5 + 1)

= {(√5 + 1)(√5 + 1)}/{(√5 - 1)(√5 + 1)} + {(√5 - 1)(√5 - 1)}/{(√5 + 1)(√5 + 1)}

= {(√5 + 1)2 }{(√5)2 - 12 } + {(√5 - 1)2 }{(√5)2 - 12 }

= (5 + 1 + 2√5)/(5 - 1) + (5 + 1 - 2√5)/(5 - 1)

= (6 + 2√5)/4 + (6 - 2√5)/4

= (6 + 2√5 + 6 - 2√5)/4

= 12/4

= 3
