Langkah 11.1

Two matrices can be multiplied if and only if the number of columns in the first matrix is equal to the number of rows in the second matrix. In this case, the first matrix is $2 \times 4$ and the second matrix is $4 \times 2$ .

Langkah 11.2

Kalikan setiap baris pada matriks pertama dengan setiap kolom pada matriks kedua.

$[\begin{array}{c} \frac{2}{7} \cdot 2 + \frac{5}{7} \cdot 5 + \frac{2}{7} \cdot 2 - \frac{4}{7} \cdot - 4 & \frac{2}{7} \cdot 3 + \frac{5}{7} \cdot 7 + \frac{2}{7} \cdot - 2 - \frac{4}{7} \cdot - 3 \\ \frac{\sqrt{22}}{22} \cdot 2 + \frac{\sqrt{22}}{11} \cdot 5 - \frac{2 \sqrt{22}}{11} \cdot 2 + \frac{\sqrt{22}}{22} \cdot - 4 & \frac{\sqrt{22}}{22} \cdot 3 + \frac{\sqrt{22}}{11} \cdot 7 - \frac{2 \sqrt{22}}{11} \cdot - 2 + \frac{\sqrt{22}}{22} \cdot - 3 \end{array}]$
