1-3i1−3i

Explanation:

To find a complex conjugate, simply change the sign of the imaginary part (the part with the ii). This means that it either goes from positive to negative or from negative to positive.

As a general rule, the complex conjugate of a+bia+bi is a-bia−bi.

Therefore, the complex conjugate of 1+3i1+3i is 1-3i1−3i.
