Question

construa a matriz d =(dij) 2x2 tal que dij 2 × i + j​

Answer 1

$\large\boxed{\begin{array}{l}\rm Construa\,a\,matriz\,d=(d_{ij})_{2\times2}\\\rm tal\,que\,d_{ij}=2\times i+j.\\\underline{\boldsymbol{soluc_{\!\!,}\tilde ao\!:}}\\\\\sf A\,matriz\,em\,quest\tilde ao\,ter\acute a\,a\,forma\\\sf d=\begin{bmatrix}\sf d_{11}&\sf d_{12}\\\sf d_{21}&\sf d_{22}\end{bmatrix}\\\underline{\rm c\acute alculo\,dos\,elementos\,da\,matriz\!:}\\\sf d_{11}=2\times1+1=3\\\sf d_{12}=2\times1+2=4\\\sf d_{21}=2\times2+1=5\\\sf d_{22}=2\times2+2=6\end{array}}$

$\Huge\boxed{\begin{array}{l}\underline{\rm A\,matriz\,pedida\,ser\acute a\!:}\\\sf d=\begin{bmatrix}\sf3&\sf4\\\sf5&\sf6\end{bmatrix}\end{array}}$
