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 $\text{z}=4-5\text{i}$ $\Rightarrow\bar{\text{z}}=4+5\text{i}$
