Question

Gente me ajuda , preciso construir uma matriz B (bij) do tipo 6x1 , sendo bij = 5i - 4j ??

Answer 1

$B= \left[\begin{array}{ccc} b_{11} \\ b_{21} \\b_{31}\\b_{41}\\b_{51}\\b_{61}\end{array}\right] = \left[\begin{array}{ccc} 5*1-4*1 \\ 5*2-4*1 \\5*3-4*1\\5*4-4*1\\5*5-4*1\\5*6-4*1\end{array}\right] = \left[\begin{array}{ccc} 1 \\ 6 \\11\\16\\21\\26\end{array}\right]$
