Question

Find the complex conjugate of the given number
1 + 3i
Write your answer in the form a + bi

Answer 1

The complex conjugate of a complex number is obtained by changing the sign of the imaginary part.

For the complex number \( 1 + 3i \), the real part is \( 1 \) and the imaginary part is \( 3i \).

Thus, the complex conjugate is:

\[
1 - 3i
\]

So, in the form \( a + bi \), the complex conjugate is \( 1 - 3i \).
