Question

Escreva a Matriz B=(bij)2x3 em que bij=4i+j.
​

Answer 1

$\mathsf{b_{11}=4.1+1=4+1=5}\\\mathsf{b_{12}=4.1+2=4+2=6}\\\mathsf{b_{13}=4.1+3=4+3=7}$

$\mathsf{b_{21}=4.2+1=8+1=9}\\\mathsf{b_{22}=4.2+2=8+2=10}\\\mathsf{b_{23}=4.2+3=8+3=11}$

$B=\begin{vmatrix}b_{11}&b_{12}&b_{13}\\b_{21}&b_{22}&b_{23}\end{vmatrix}\\B=\begin{vmatrix}5&6&7\\9&10&11\end{vmatrix}$
