\[
\textbf{Multiply Matrix A (1×3) by Matrix B (3×1), where:}
\]
\[
A = \begin{pmatrix} 2 & 4 & 6 \end{pmatrix}, \quad B = \begin{pmatrix} 1 \\ 3 \\ 5 \end{pmatrix}
\]
\[
\textbf{Solution:}
\]
\[
A \times B = \begin{pmatrix} 2 & 4 & 6 \end{pmatrix} \times \begin{pmatrix} 1 \\ 3 \\ 5 \end{pmatrix}
\]
\[
= (2 \cdot 1 + 4 \cdot 3 + 6 \cdot 5)
\]
\[
= 2 + 12 + 30 = 44
