Question

Construa a matriz b= 2x2 tal que bij= j2+3.i

Answer 1

|b11 b12| b= 1.2+3.1=5       |5  8|
|b21 b22| b=1.2+3.2=8        |7 10|
                b=2.2+3.1=7
                b=2.2+3.2=10   

Answer 2

B11= 1² + 3 x 1 = 1+3=4
B12= 2² + 3 x 1 = 4+3=7

B21= 1² + 3 X 2 = 1+6=7
B22= 2² + 3 X 2 = 4+6=10

4    7

7    10
