Answer» Correct Answer - A `(sqrt(5+2sqrt(6))-1/(sqrt(5+2sqrt(6)))` `implies (sqrt(3)+sqrt(2))-1/((sqrt(3)+sqrt(2)))` `[(sqrt(5+2sqrt(6))=sqrt((sqrt(3)+sqrt(2))^(2))impliessqrt(3)+sqrt(2)),(a^(2)+b^(2)+2ab=(a+b)^(2))]` `impliessqrt(3)+sqrt(2)-(1/(sqrt(3)+sqrt(2))xx(sqrt(3)-sqrt(2))/(sqrt(3)-sqrt(2)))` `impliessqrt(3)+sqrt(2)-((sqrt(3)-sqrt(2))/(3-2))` `impliessqrt(3)+sqrt(2)-sqrt(3)+sqrt(2)` `implies 2sqrt(2)` |
