Write the number of all possible matrices of order `2xx2` with each entry 1, 2 or 3.

Explanation

To find the number of all possible matrices of order \(2 \times 2\) with each entry being either 1, 2, or 3, we can follow these steps:

### Step 1: Understand the Structure of the Matrix
A \(2 \times 2\) matrix has 2 rows and 2 columns. Therefore, it contains a total of 4 elements. We can denote the matrix as follows:

\[
\begin{pmatrix}
a_{11} & a_{12} \\
