Step 1 :Firstly, we multiply each component of the vector \( \mathbf{v} \) by the scalar \( 5 \): \( 5 \times \begin{bmatrix} 2 \ \ 3 \ \ 4 \end{bmatrix} \)
Step 2 :Then we get: \( \begin{bmatrix} 5 \times 2 \ \ 5 \times 3 \ \ 5 \times 4 \end{bmatrix} \)
Step 3 :Finally, we simplify the multiplication: \( \begin{bmatrix} 10 \ \ 15 \ \ 20 \end{bmatrix} \)
