Answer 1

a) 2+3i/1+2i (2+3i).(1-2i) / (1+2i).(1-2i) = (2-4i+3i-6i²) / (1-4i²) = (2-i+6) / (1+4) = (8-i) / 5 B) 1 /(3+2i) = (3-2i) / (3+2i).(3-2i) = (3 -2i) / (9-4i²) = (3 - 2i) / ( 9+4) = (3 -2i) / 13 c) (1+3i) / (1-i) = (1+3i).(1+i) / (1-i).(1+i) = (1+i+3i+3i²) / (1 -i²) (1+4i-3) / (1+1) = (-2+4i) / 2 = -1 +2i Também to fazendo isso, mas so responde ate ai
