Explicação passo-a-passo:

$C_{(3x2)} \:\:\: (cij) = (-1)^i + j$

$C = \large\mathsf{\begin{vmatrix}c_{11}&c_{12}\\c_{21}&c_{22}\\c_{31}&c_{32}\end{vmatrix}} = \large\mathsf{\begin{vmatrix}(-1)^1 + 1&(-1)^1 + 2\\(-1)^2 + 1&(-1)^2 + 2\\(-1)^3 + 1&(-1)^3 + 2\end{vmatrix}} = \large\mathsf{\begin{vmatrix}0&1\\2&3\\0&1\end{vmatrix}}$
