Question

construa a matriz quadrada de ordem 3, B = (bij), Sendo bij= 2i - 3j.

Answer 1

b11= 2.1 - 3.1 = 2 - 3 = -1
b12= 2.1 - 3.2 = 2 - 6 = -4
b13= 2.1 - 3.3 = 2 - 9 = -7

b21= 2.2 - 3.1 = 4 - 3 = 1
b22= 2.2 - 3.2 = 4 - 6 = -2
b23= 2.2 - 3.3 = 4 - 9 = -5

b31= 2.3 - 3.1 = 6 - 3 = 3
b32= 2.3 - 3.2 = 6 - 6 = 0
b33= 2.3 - 3.3 = 6 - 9 = -3


Matriz B

| -1 -4 -7|
|. 1 -2 -5|
| 3. 0 -3|
