Question

What is the order of \[A=\begin{bmatrix}0\\ \sqrt{3}\\ -1\\ \dfrac{1}{2}\end{bmatrix}\]?

Options

• \[4 \times 1\]

• \[3 \times 1\]

• \[4 \times 4\]

• \[1 \times 4\]

Answer 1

The matrix has four rows containing \[0,\sqrt{3},-1,\dfrac{1}{2}\]. It has only one column, so it is a column matrix of order \[4 \times 1\].
