Answer 1

Answer:

22

Step-by-step explanation:

this needs to be solve very lOng but I have a trick on it

Answer 2

it is not clearly visible but I am trying to answer..

x= √5-1/√5+1 = (√5-1)×(√5-1)/(√5+1)×(√5-1)

= (√5-1)²/√5²-1²

= 5-2×√5×1+1² / 4 = 6-2√5/ 4

Y= √5+1/√5-1 = (√5+1)×(√5+1)/(√5-1)×(√5+1)

= 5+ 2√5+1 / (√5²-1²)

= 6+2√5/4

now....

x²/y+y²/x= {(5-2√5/4)²/6+2√5/4} + {(6+2√5/4)²/6-2√5/4

now. u can solve it...
