Question

How do you write the complex conjugate of the complex number `4-2i`?

Answer 1

The complex conjugate is `4+2i`

Explanation:

To find the complex conjugate of a number you just have to change the sign of its imaginary part to opposite. So if

`z=4-2i`

then its conjugate is:

`bar(z)=4color(red)(+)2i`
