☺lá, Rafaela, como tens passado nestes tempos de quarentena⁉ E os estudos à distância, como vão⁉ Espero que bem❗ Acompanhe a construção desta matriz pelos passos a baixo, ressaltando que i representa a linha em que o nosso elemento $a_{i, j}$ está e j representa a coluna em que ele está.✌

$\sf\large\blue{A_{4,4}=\left[\begin{array}{cccc}2i + 3j&2i + 3j&2i + 3j&2i + 3j\\\\2i + 3j&2i + 3j&2i + 3j&2i + 3j\\\\2i + 3j&2i + 3j&2i + 3j&2i + 3j\\\\2i + 3j&2i + 3j&2i + 3j&2i + 3j\\\end{array}\right]}$

.

$\sf\large\blue{A_{4,4}=\left[\begin{array}{cccc}2 \cdot (1) + 3 \cdot (1)&2 \cdot (1) + 3 \cdot (2)&2 \cdot (1) + 3 \cdot (3)&2 \cdot (1) + 3 \cdot (4)\\\\2 \cdot (2) + 3 \cdot (1)&2 \cdot (2) + 3 \cdot (2)&2 \cdot (2) + 3 \cdot (3)&2 \cdot (2) + 3 \cdot (4)\\\\2 \cdot (3) + 3 \cdot (1)&2 \cdot (3) + 3 \cdot (2)&2 \cdot (3) + 3 \cdot (3)&2 \cdot (3) + 3 \cdot (4)\\\\2 \cdot (4) + 3 \cdot (1)&2 \cdot (4) + 3 \cdot (2)&2 \cdot (4) + 3 \cdot (3)&2 \cdot (4) + 3 \cdot (4)\\\end{array}\right]}$

.

$\sf\large\blue{A_{4,4}=\left[\begin{array}{cccc}2 + 3&2 + 6&2 + 9&2 + 12\\\\4 + 3&4 + 6&4 + 9&4 + 12\\\\6 + 3&6 + 6&6 + 9&6 + 12\\\\8 + 3&8 + 6&8 + 9&8 + 12\\\end{array}\right]}$

.

$\sf\large\blue{A_{4,4}=\left[\begin{array}{cccc}5&8&11&14\\\\7&10&13&16\\\\9&12&15&18\\\\11&14&17&20\\\end{array}\right]}$
