Question

Construir a matriz (Aij) 2x2, tal que Aij= i² 3j + i.j Desde ja agradeço a quem me ajudar.

Answer 1

$A= \left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\end{array}\right] \\ \\ A= \left[\begin{array}{ccc}{1^2.3.1+1.1}&{1^2.3.2+1.2}\\{2^2.3.1+2.1}&{2^2.3.2+3.2}\end{array}\right] \\ \\ A= \left[\begin{array}{ccc}{5}&{8}\\{14}&{30}\end{array}\right]$
