Question

escreva a matriz B= ( bij ) 4×2 , na qual aij =2i+5​

Answer 1

Explicação passo-a-passo:

B = b11 b12

b21 b22

b31 b32

b41 b42

bij= 2i +5

b11= 2.1+5 = 2+5=7

b12= 2.1+5= 7

b21= 2.2+5= 4+5=9

b22= 2.2+5= 4+5=9

b31= 2.3+5= 6+5=11

b32= 2.3+5= 11

b41= 2.4+5= 8+5= 13

b42= 2.4+5= 13

B = 7 7

9 9

11 11

13 13
