Given that A = 2 & 1 3 & 4 and B = 1 & 0 2 & 3 .

Here are the solutions to the problems.

1. Given that $A = \begin{bmatrix} 2 & 1 \\ 3 & 4 \end{bmatrix}$ and $B = \begin{bmatrix} 1 & 0 \\ 2 & 3 \end{bmatrix}$.

a) Find $AB$.

Step 1: Multiply matrix $A$ by matrix $B$.

$$AB = \begin{bmatrix} 2 & 1 \\ 3 & 4 \end{bmatrix} \begin{bmatrix} 1 & 0 \\ 2 & 3 \end{bmatrix}$$

Step 2: Perform the matrix multiplication.
