Answer:
(-5 -1i)
Step-by-step explanation:
You first add (3 - 8)...(it will be negative 8 because you'll use the sign of the bigger number) you'll get (-5)
Then you'll add 5i + (-6i)...remember you'll use sign of the bigger number so you'll get (-1i)
And all together it will be (-5 -1i)
Hope you understand :)
