Answer:
The answer is 6 – 4i
Step-by-step explanation:
Complex values:
Have the following format: a + bi
In which a is the real part and b is the complex part.
Addition:
Suppose we are going to add two complex numbers. We add their real parts, and their complex parts separatly.
So
(–4 + i) + (10 – 5i) = (-4 + 10) + i(1-5) = 6 - 4i
The answer is 6 – 4i
Answer:
for the first question it is (9 + 4i) + (–1 – 7i)
and for the second one it is
6 – 4i
