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

Jul 10, 2016

The complex conjugate is $4 + 2 i$

#### Explanation:

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

$z = 4 - 2 i$

then its conjugate is:

$\overline{z} = 4 \textcolor{red}{+} 2 i$
