Answer:
B. (13/3 - 3i)
Step-by-step explanation:
Given: (3i - 2/3) - (6i - 5)
Here we have to subtract.
To simplify we have to combine real numbers and complex number(i.e) terms with "i"
= 3i - 2/3 -6i + 5 [distributed the negative sign inside the parenthesis]
= -2/3 + 5 + 3i - 6i[Combine real numbers and complex numbers]
= 13/3 - 3i
Therefore, the answer is B. (13/3 - 3i)
Hope this will helpful.
Thank you.
