If the matrices \[A=\left[\begin{array}{lll}
2 & 1 & 3 \\
4 & 1 & 0
\end{array}\right] \text { and } B=\left[\begin{array}{cc}
1 & -1 \\
0 & 2 \\
5 & 0
\end{array}\right] .\] then AB will be
- \(\left[\begin{array}{cc} 17 & 0 \\ 4 & -2 \end{array}\right]\)
- \(\left[\begin{array}{ll} 4 & 0 \\ 0 & 4 \end{array}\right]\)
- \(\left[\begin{array}{cc} 17 & 4 \\ 0 & -2 \end{array}\right]\)
- \(\left[\begin{array}{ll} 0 & 0 \\ 0 & 0 \end{array}\right]\)
Answer
(A) [ array cc 17 & 0 4 & -2 array ]
