Question

construa a matriz A(aij), do tipo 2*3 sabendo que aij = 2i 3j-4

Answer 1

$A_{2x3}=\left[\begin{array}{ccc}a_{11}&b_{12}&c_{13}\\d_{21}&e_22}&f_{23}\\\end{array}\right]\\\\ a_{11}=2*1+3*1-4=1\\ a_{12}=2*1+3*2-4=4\\ a_{13}=2*1+3*3-4=6\\ a_{21}=2*2+3*1-4=3\\ a_{22}=2*2+3*2-4=4\\ a_{23}=2*2+3*3-4=9\\\\ A_{2x3}=\left[\begin{array}{ccc}1&4&6\\3&4&9}\\\end{array}\right]$
