Question

escreva a matriz A= (aij) 3× 4 na qual aij = 3i + 2j

Answer 1

Olá!!!



a11= 3.1 + 2.1 → 3 + 2 = 5
a12= 3.1 + 2.2 → 3 + 4 = 7
a13= 3.1 + 2.3 → 3 + 6 = 9
a14= 3.1 + 2.4 → 3 + 8 = 11

a21= 3.2 + 2.1 → 6 + 2 = 8
a22= 3.2 + 2.2 → 6 + 4 = 10
a23= 3.2 + 2.3 → 6 + 6 = 12
a24= 3.2 + 2.4 → 6 + 8 = 14

a31= 3.3 + 2.1 → 9 + 2 = 11
a32= 3.3 + 2.2 → 9 + 4 = 13
a33= 3.3 + 2.3 → 9 + 6 = 15
a34= 3.3 + 2.4 → 9 + 8 = 17



Matriz A


| 5 ..7.. 9 11 |
| 8 10 12 14 |
| 11 13 15 17 |
