Question

Construa a matriz B3x4 onde bij=i-2j+2

Answer 1

b11 b12 b13 b14
b21 b22 b23 b24
b31 b32 b33 b34

b11= 1-2.1+2= 1       b21= 2-2.1+2= 2
b12= 1-2.2+2= -1      b22= 2-2.2+2= 0
b13= 1-2.3+2= -3      b23= 2-2.3+2= -2
b14= 1-2.4+2= -5      b24= 2-2.4+2= -4

b31= 3-2.1+2= 3      b41= 4-2.1+2= 4
b32= 3-2.2+2= 1      b42= 4-2.2+2= 2
b33= 3-2.3+2= -1     b43= 4-2.3+2= 0
b34= 3-2.4+2= -3     b44= 4-2.4+2= -2
