Question

Escreva a matriz.......

Answer 1

Explicação passo-a-passo:

$A=\left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\end{array}\right]$

$a_{ij}=3i-2j$

$a_{11}=3.1-2.1=3-2=1\\a_{12}=3.1-2.2=3-4=-1\\a_{21}=3.2-2.1=6-2=4\\a_{22}=3.2-2.2=6-4=2$

$A=\left[\begin{array}{ccc}1&-1\\4&2\end{array}\right]$
