इनमें से सबसे छोटी संख्या कौन सी है? `sqrt(8)+sqrt(5),sqrt(7)+sqrt(6),sqrt(10)+sqrt(3)` and `sqrt(11)+sqrt(2)`A. `sqrt(8)+sqrt(5)`B. `sqrt(7)+sqrt(6)`C. `sqrt(10)+sqrt(3)`D. `sqrt(11)+sqrt(2)` |

Answer» Correct Answer - D `sqrt(8)+sqrt(5)=(sqrt(8)+sqrt(5))^(2)` `=8+5+2sqrt(40)=13+2sqrt(40)` `(sqrt(7)+sqrt(6))implies(sqrt(7)+sqrt(6))^(2)implies7+6+2sqrt(42)` `implies 13+2sqrt(42)` `implies(sqrt(10)+sqrt(3))implies(sqrt(10)+sqrt(3))^(2)` `implies10+3+2sqrt(30)implies13+2sqrt(30)` `impliessqrt(11)+sqrt(2)implies(sqrt(11)+sqrt(2))^(2)` `implies 11+2+2sqrt(22)implies13+2sqrt(22)` `sqrt(11)+sqrt(12)` |
