Answer:
Step-by-step explanation:
<u>Given:</u>
<u>Conjugate of the given number is:</u>
<u>Divide the given number by its conjugate:</u>
- (4 - 3i) / (4 + 3i) =
- (4 - 3i)(4 - 3i) / (4 + 3i)(4 - 3i) =
- (16 + 9i² - 24i) / (16 - 9i²) =
- (16 - 9 - 24i) / (16 + 9) =
- (7 - 24i) / 25 =
- 7/25 - 24i/25
