Explicação passo-a-passo:

$A = \large\mathsf{\begin{vmatrix}1&2\\0&4\\1&8\end{vmatrix}}$

$B = \large\mathsf{\begin{vmatrix}2&1\\3&4\end{vmatrix}}$

$AB = \large\mathsf{\begin{vmatrix}1&2\\0&4\\1&8\end{vmatrix}}.\large\mathsf{\begin{vmatrix}2&1\\3&4\end{vmatrix}} = \large\mathsf{\begin{vmatrix}2+6&0 + 12&2+ 24\\1 + 8&0 + 16&1+32\end{vmatrix}} = \large\mathsf{\begin{vmatrix}8&12&26\\9&16&33\end{vmatrix}}$
