Let&nbsp;$z=x+y\text{i}$. The conjugate of ${{z}^{*}}$, is defined by ${{z}^{*}}=x-yi$. Example:
If&nbsp;$z=6+7\mathbf{i}$, then&nbsp;${{z}^{*}}=6-7\mathbf{i}$ If&nbsp;$z=-4-\mathbf{i}$, then&nbsp;${{z}^{*}}=\text{}\hspace{0.5em}$ If&nbsp;$z=-\mathbf{i}$, then&nbsp;${{z}^{*}}=\text{}\hspace{0.5em}$ If&nbsp;$z=4$, then&nbsp;${{z}^{*}}=\text{}\hspace{0.5em}$

Let $z=x+y\text{i}$. The conjugate of ${{z}^{*}}$, is defined by ${{z}^{*}}=x-yi$.
Example:

If $z=6+7\mathbf{i}$, then ${{z}^{*}}=6-7\mathbf{i}$
If $z=-4-\mathbf{i}$, then ${{z}^{*}}=\text{ }$
If $z=-\mathbf{i}$, then ${{z}^{*}}=\text{ }$
If $z=4$, then ${{z}^{*}}=\text{ }$
