Answer» Correct Answer - A `1/(sqrt(3.25)+sqrt(2.25))xx(sqrt(3.55)-sqrt(2.25))/(sqrt(3.25)-sqrt(2.25))` `implies (sqrt(3.25)-sqrt(2.25))/(3.25-2.25)` `impliessqrt(3.25)-sqrt(2.25)`……………i Similarly : `1/(sqrt(4.25)+sqrt(3.25))` `impliessqrt(4.25)-sqrt(3.25)`………….ii `implies1/(sqrt(5.25)-sqrt(4.25))` `impliessqrt(5.25)-sqrt(4.25)`..........iii `implies1/(sqrt(6.25)+sqrt(5.25))` `implies sqrt(6.25)-sqrt(5.25)`...........iv `implies` Now add all them `impliessqrt(3.25)-sqrt(2.25)+sqrt(4.25)-sqrt(3.25)` `+sqrt(5.25)-sqrt(4.25)+sqrt(6.25)-sqrt(5.25)` `implies sqrt(6.25)-sqrt(2.25)implies2.5-1.5=1` |
