Answer 1

Resposta:

$\left[\begin{array}{cc}3&4\\5&6\end{array}\right]$

Explicação passo-a-passo:

A = ( aij ) 2×2 onde a ij = 2i + j​

$\left[\begin{array}{cc}a11&a12\\a21&a22\end{array}\right]$

=

$\left[\begin{array}{cc}2.1 + 1&2 . 1 + 2\\2.2 + 1&2.2 + 2\end{array}\right]$

=

$\left[\begin{array}{cc}3&4\\5&6\end{array}\right]$
