HERE IS THE SOLUTION :
= 5 / √ 5 - 2 √ 3 * √ 5 + 2 √ 3 / √ 5 + 2 √ 3
= 5 ( √ 5 + 2 √ 3 ) / ( √ 5 ) ^ 2 - ( 2 √ 3 ) ^ 2
= 5 √ 5 + 10 √ 3 / 5 - 12
= 5 √ 5 + 10 √ 3 / - 7
SOLUTION = 5 ( √ 5 + 2 √ 3 ) / - 7
HOPE IT HELPED.. :))
= 5 / √ 5 - 2 √ 3 * √ 5 + 2 √ 3 / √ 5 + 2 √ 3
= 5 ( √ 5 + 2 √ 3 ) / ( √ 5 ) ^ 2 - ( 2 √ 3 ) ^ 2
= 5 √ 5 + 10 √ 3 / 5 - 12
= 5 √ 5 + 10 √ 3 / - 7
SOLUTION = 5 ( √ 5 + 2 √ 3 ) / - 7
