Question

Add the complex numbers. Enter your answer into the box. (2 points) (3−5i)+(8+7i) =

Answer 1

To add the complex numbers \( (3 - 5i) + (8 + 7i) \), we 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 the results:
\[
11 + 2i
\]

So, the final answer is:
\[
\boxed{11 + 2i}
\]
