Question
Add the following complex numbers:(5 - 3i) + (10 + 5i)A.-5 + 2iB.15 + 8iC.-5 + 8iD.15 + 2iSUBMITarrow_backPREVIOUS
Solution
To add complex numbers, you simply add the real parts together and the imaginary parts together.
The real parts are 5 and 10. If you add these together, you get 15.
The imaginary parts are -3i and 5i. If you add these together, you get 2i.
So, (5 - 3i) + (10 + 5i) = 15 + 2i.
Therefore, the correct answer is D.15 + 2i.
