Question

Escreva a matriz B = (bij)3×4, sabendo que bij = 2i -3j​

Answer 1

Explicação passo-a-passo:

|b11 b12 b13 b14|

|b21 b22 b23 b24|

|b31 b32 b33 b34|

|b41 b42 b43 b44|

bij=2i-3j

b11=2(1)-3(1)

b11=2-3

b11=-1

b12=2(1)-3(2)

b12=2-6

b12=-4

b13=2(1)-3(3)

b13=2-9

b13=-6

b14=2(1)-3(4)

b14=2-12

b14=-10

b21=2(2)-3(1)

b21=4-3

b21=1

b22=2(2)-3(2)

b22=4-6

b22=-2

b23=2(2)-3(3)

b23=4-9

b23=-3

b24=2(2)-3(4)

b24=4-12

b24=-8

b31=2(3)-3(1)

b31=6-3

b31=3

b32=2(3)-3(2)

b32=6-6

b32=0

b33=2(3)-3(3)

b33=6-9

b33=-3

b34=2(3)-3(4)

b34=6-12

b34=-6

b41=2(4)-3(1)

b41=8-3

b41=5

b42=2(4)-3(2)

b42=8-6

b42=2

b43=2(4)-3(3)

b43=8-9

b43=-1

b44=2(4)-3(4)

b44=8-12

b44=-4

|-1 -4 -6 -10|

| 1 -2 -3 -8 |

| 3 0 -3 -6 |

| 5 2 -1 -4 |
