Question

construa a matriz de ordem 2x3 tal que aij = i-j

Answer 1

Bom dia!

i = 2 | j = 3

Matriz;

$\begin{bmatrix}a11&a12&a13\\a21&a22&a23\\\end{bmatrix}$

$\mathrm{a11}\Rightarrow\mathrm{1-1}=\boxed{0}$

$\mathrm{a12}\Rightarrow\mathrm{1-2}=\boxed{-1}$

$\mathrm{a13}\Rightarrow\mathrm{1-3}=\boxed{-2}$

$\mathrm{a21}\Rightarrow\mathrm{2-1}=\boxed{1}$

$\mathrm{a22}\Rightarrow\mathrm{2-2}=\boxed{0}$

$\mathrm{a23}\Rightarrow\mathrm{2-3}=\boxed{-1}$

Matriz resposta;

$\begin{bmatrix}0&-1&-2\\1&0&-1\\\end{bmatrix}$
