Question

Write the additive inverse of the following :A) -2+3iB) 3-4i

Answer 1

$$\begin{gathered} \left(1\right). \\ \mathrm{Let}\mathrm{z}=\left(-2+3\mathrm{i}\right) \\ \mathrm{Now},\mathrm{additive}\mathrm{inverse}\mathrm{of}\mathrm{z}=-\mathrm{z}=-\left(-2+3\mathrm{i}\right)=2-3\mathrm{i} \\ \left(2\right). \\ \mathrm{Let}\mathrm{z}=3-4\mathrm{i} \\ \mathrm{Now},\mathrm{additive}\mathrm{inverse}\mathrm{of}\mathrm{z}=-\mathrm{z}=-\left(3-4\mathrm{i}\right)=-3+4\mathrm{i} \end{gathered}$$
