Question

B = (bij)3x3, em que cij = i + j

Answer 1

A matriz 3x3 sera:
| b11 b12 b13 |
| b21 b22 b23 |
| b31 b32 b33 | 3x3

bij= i + j
| b11 = 1 + 1 = 2 |
| b12 = 1 + 2 = 3 |
| b13 = 1 + 3 = 4 |

|b21 = 2 + 1 = 3|
|b22 = 2 + 2 = 4|
|b23 = 2 + 3 = 5 |

| b31 = 3 + 1 = 4 |
| b32 = 3 + 2 = 5|
| b 33 = 3 + 3 = 6|

Assim formará a matriz:
| 2 3 4 |
| 3 4 5 |
| 4 5 6 | .
