1.	(i) If A=[3√32420] and B=[2−12124], verify that (A′)′=A.(ii) If A=[3√32420] and B=[2−12124], verify that (A+B)′=A′+B′.(iii) If A=[3√32420] and B=[2−12124], verify that (kB)′=(kB′) where k is any constant.
Answer» $(i)$ If $A = [\begin{matrix} 3 & \sqrt{3} & 2 4 & 2 & 0 \end{matrix}]$ and $B = [\begin{matrix} 2 & - 1 & 2 1 & 2 & 4 \end{matrix}]$ , verify that $(A^{'})^{'} = A .$ $(i i)$ If $A = [\begin{matrix} 3 & \sqrt{3} & 2 4 & 2 & 0 \end{matrix}]$ and $B = [\begin{matrix} 2 & - 1 & 2 1 & 2 & 4 \end{matrix}]$ , verify that $(A + B)^{'} = A^{'} + B^{'} .$ $(i i i)$ If $A = [\begin{matrix} 3 & \sqrt{3} & 2 4 & 2 & 0 \end{matrix}]$ and $B = [\begin{matrix} 2 & - 1 & 2 1 & 2 & 4 \end{matrix}]$ , verify that $(k B)^{'} = (k B^{'})$ where $k$ is any constant.
