Question

What is the order of \[A=\begin{bmatrix}3&-1&0\\ \dfrac{3}{2}&3\sqrt{2}&1\\ 4&3&-1\end{bmatrix}\]?

पर्याय

• Square matrix of order \[3\]

• Column matrix of order \[3 \times 1\]

• Row matrix of order \[1 \times 3\]

• Diagonal matrix of order \[3\]

Answer 1

This matrix has three rows and three columns. It is therefore a square matrix of order \[3\], although its non-diagonal elements are not all zero.
