Question

Ache a matriz A do tipo 2x3 definida por aij= i.j onde i indica linha e j, a coluna.
R= $\left[\begin{array}{ccc}1&2&3\\2&4&6\end{array}\right]$

Answer 1

$Ola' \\ \\ Seja~a~matriz ~A=\begin{pmatrix}a_{11}&a_{12}&a_{13} \\ a_{21}&a_{22}&a_{23}\end{pmatrix}_{2_X3}$

$onde~indica:~\boxed{a_{ij}=i.j} \\ a_{11}=1.1=1 \\ a_{12}=1.2=2 \\ a_{13}=1.3=3 \\ a_{21}=2.1=2 \\ a_{22}=2.2=4 \\ a_{23}=2.3=6$

$A=\begin{vmatrix}1&2&3 \\ 2&4&6\end{vmatrix}_{2_X3}\\ \\ \\ \mathbb{ttttttttttttttttttttttttttttttttttttt} \\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Espero~ter~ajudado!!$
