    				| 1. | `((3-2i)(2 + 3i))/((1 + 2i) (2 -i))` का संयुग्मी ज्ञात कीजिए। | 
| Answer» `((3 - 2i)(2 + 3i))/((1 + 2i) (2 -i)) = (3 (2 + 3i) - 2i (2 + 3i))/(1 (2 -i) + 2i (2 -i))` `= (6 + 9i -4i - 6i^(2))/(2 - i + 4i - 2i^(2))` `= (6 + 5i + 6)/(2 + 3i + 2)` `= (12 + 5i)/(4 + 3i) xx (4 - 3i)/(4 - 3i)` `= (12 (4 - 3i) + 5i(4 - 3i))/((4)^(2) - (3i)^(2))` `= (48 - 36i + 20i - 15i^(2))/(16 - 9i^(2))` `= (48 - 16i + 15)/(16 + 9) = (63 - 16i)/(25)` अत: `((3 -2i) (2 + 3i))/((1 + 2i) (2 - i))` का संयुग्मी `(63)/(25) - (16)/(25)i` | |
