Question

construa a matriz A(aij)3x2 tal que aij=2i+j

Answer 1

$A= \left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\\a_{31}&a_{32}\end{array}\right] \\ \\ A= \left[\begin{array}{ccc}{2.1+1}&{2.1+2}\\{2.2+1}&{2.2+2}\\{2.3+1}&{2.3+2}\end{array}\right] \\ \\ A= \left[\begin{array}{ccc}{3}&{4}\\{5}&{6}\\{7}&{8}\end{array}\right]$

Answer 2

Explicação passo-a-passo:

A=⎣⎢⎡a11a21a31a12a22a32⎦⎥⎤A=⎣⎢⎡2.1+12.2+12.3+12.1+22.2+22.3+2⎦⎥⎤A=⎣⎢⎡357468⎦⎥⎤
