Question

How do you find the complex conjugate of `12 + 7i`?

Answer 1

`12-7i`

Explanation:

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

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

Therefore, the complex conjugate of `12+7i` is `12-7i`.
