Question
Find the conjugates of the following complex numbers:
$4-5\text{i}$
✓

Answer

If $\text{z}=\text{x}+\text{iy}$ is a complex number, then the conjugate of z denoted by $\bar{\text{z}}$ is defined as $\bar{\text{z}}=\text{x}-\text{iy}$
Let $\text{z}=4-5\text{i}$
$\Rightarrow\bar{\text{z}}=4+5\text{i}$
