(11, 13)
\(\begin{pmatrix} 13 \\ 11 \end{pmatrix}\)
\(\begin{pmatrix} 11 \\ 13 \end{pmatrix}\)
Correct answer is C
\(\begin{pmatrix} 2 & 3 \\ 4 & 1 \end{pmatrix} \begin{pmatrix} 2 \\ 3 \end{pmatrix}\)
= \(\begin{pmatrix} 2 \times 2 + 3 \times 3 \\ 4 \times 2 + 1 \times 3 \end{pmatrix}\)
= \(\begin{pmatrix} 13 \\ 11 \end{pmatrix}\)
