Question

Add the complex numbers.

(3-5i)+(8+7i) =

Answer 1

To add the complex numbers \( (3 - 5i) \) and \( (8 + 7i) \), you combine the real parts and the imaginary parts separately.

1. **Add the real parts**:
\( 3 + 8 = 11 \)

2. **Add the imaginary parts**:
\( -5i + 7i = 2i \)

Now combine these results:

\[
(3 - 5i) + (8 + 7i) = 11 + 2i
\]

So, the final result is:

\[
11 + 2i
\]
