A) \[\left[ \begin{matrix} 1 & 1 \\ 1 & 1 \\ \end{matrix} \right]\]
B) \[\left[ \begin{matrix} 0 & 1 \\ -1 & 0 \\ \end{matrix} \right]\]
C) \[\left[ \begin{matrix} 0 & -1 \\ 1 & 0 \\ \end{matrix} \right]\]
D) \[\left[ \begin{matrix} -1 & 0 \\ 0 & 0 \\ \end{matrix} \right]\]
Correct Answer: D
Solution :
Since \[\left[ \begin{matrix} 0 & 1 \\ 0 & 0 \\ \end{matrix} \right]\,\left[ \begin{matrix} -1 & 0 \\ 0 & 0 \\ \end{matrix} \right]=\left[ \begin{matrix} 0 & 0 \\ 0 & 0 \\ \end{matrix} \right]=O=AB\] Þ \[B=\left[ \begin{matrix} -1 & 0 \\ 0 & 0 \\ \end{matrix} \right]\].You need to login to perform this action.
