Answer 1

Olá, Joice.

 

$B=(<var>b_{ij})_{2\times2},\ onde:\ b_{ij} = (i-j)\cdot2=2(i-j)\\\\ b_{11}=2(1-1)=0 \\ b_{12}=2(1-2)=-2 \\ b_{21}=2(2-1)=2 \\ b_{22}=2(2-2)=0 \\\\ B=\left[\begin{array}{cc}b_{11}&b_{12}\\b_{21}&b_{22}\end{array}\right]=\left[\begin{array}{cc}0&-2\\2&0\end{array}\right]</var>$
