Respuesta :

1. (7 βˆ’ 3i) β€’ (2 βˆ’ i)
It is simplified as follows:
14Β -Β 7i Β -6i -Β 3
11 - 13i

2. (βˆ’5 + 3i) β€’ (1 βˆ’ 2i)Β 
It is simplified as follows:
-5 + 10i + 3i + 6
1 + 13i

3. (1 + 3i) + (2 βˆ’ 5i)Β 
It is simplified as follows:
1 + 3i + 2 βˆ’ 5i
3 - 2i

4. (6 + 2i) βˆ’ (8 βˆ’ 3i)Β 
It is simplified as follows:
6 + 2i βˆ’ 8 + 3i
-2 + 5i

Answer:1 + 13i
