`sqrt(11+2sqrt(30))-1/(sqrt(11+2sqrt(30))` का मान ज्ञात करें।A. `2sqrt(5)`B. `2sqrt(6)`C. `1+sqrt(6)`D. `1+sqrt(5)` |

Answer» Correct Answer - A `sqrt(11+2sqrt(30))-1/(sqrt(11+2sqrt(30)))` `impliessqrt((sqrt(6))^(2)+(sqrt(5))^(2)+2sqrt(6).sqrt(5))` `-1/(sqrt((sqrt(6))^(2)+(sqrt(5))^(2)+2sqrt(6).sqrt(5)))` `impliessqrt((sqrt(6)+sqrt(5))^(2))-1/(sqrt((sqrt(6)+sqrt(5))^(2)))` `impliessqrt(6)+sqrt(5)-1/(sqrt(6)+sqrt(5))` Relationalising above question `impliessqrt(6)+sqrt(5)-1/(sqrt(6)+sqrt(5))xx(sqrt(6)-sqrt(5))/(sqrt(6)-sqrt(5))` `impliessqrt(6)+sqrt(5)-(sqrt(6)-sqrt(5))` `impliessqrt(6)+sqrt(5)-sqrt(6)+sqrt(5)` `implies2sqrt(5)` |
