Question

There are 3 complex numbers a+bi, c+di, and e+fi. If b=3, e=-a-c, and the sum of the numbers is 2i, find d+f.

Answer 1

Answer:

-1

Step-by-step explanation:

Since the sum is imaginary hence the real part is not important here.

Now the sum of imaginary part is

b+ d+f = 2 or d + f = 2 -3 = -1 ; as b = 3.
