Question

gostaria que alguém respondesse estas matrizes para mim.
2x3 a i j = i - j
2x2 a i j = i + j
3x2 a i j = 2i - j
3x3 a i j =2i + j

Answer 1

$\left[\begin{array}{ccc}a11&a12&a13\\a21&a22&a23\\\end{array}\right] = \left[\begin{array}{ccc}(1-1)&(1-2)&(1-3)\\(2-1)&(2-2)&(2-3)\\\end{array}\right] = \left[\begin{array}{ccc}0&-1&-2\\1&0&-1\\\end{array}\right]$

$Matriz 3x2(2i-j) \\ \left[\begin{array}{cc}a11&a12\\a21&a22\\a31&a32\end{array}\right] = \left[\begin{array}{cc}(2.1-1)&(2.1-2)\\(2.2-1)&(2.2-2)\\(2.3-1)&(2.3-2)\end{array}\right] =\left[\begin{array}{cc}1&0\\3&2\\5&4\end{array}\right]$
