Пошаговое объяснение:

= 2 + i + 3 + i - 4 + 5i =

(2 + 3 - 4) + (i + i + 5i) =

1 + 7i

Ответ: 1 + 7i

Answer 3

To add complex numbers, you simply add the real parts together and the imaginary parts together. In this case:

(2 + i) + (3 + i) + (-4 + 5i)

Adding the real parts: 2 + 3 - 4 = 1

Adding the imaginary parts: 1i + 1i + 5i = 7i

So, the result is 1 + 7i.
