Question

lConstrua a matriz B = (aij) do tipo 2x3, tal que aij = i + j - 2 *​

Answer 1

$\Large\boxed{\begin{array}{l}\sf B=(b_{ij})_{2\times3},a_{ij}=i+j-2\\\sf a_{11}=1+1-2=0\\\sf a_{12}=1+2-2=1\\\sf a_{13}=1+3-2=2\\\sf a_{21}=2+1-2=1\\\sf a_{22}=2+2-2=2\\\sf a_{23}=2+3-2=3\\\sf B=\begin{bmatrix}\sf0&\sf1&\sf2\\\sf1&\sf2&\sf3\end{bmatrix}\end{array}}$
