Question

p= (pij)3×2, tal que pij=4i+j³​

Answer 1

p= { (pij)3×2 | pij=4i+j³ }

pij ,p11= 4(1) +(1)³= 4+1 = 5
pij ,p12= 4(1) +(2)³= 4+8 =12
pij ,p21= 4(2) +(1)³= 8+1 = 9
pij ,p22= 4(2) +(2)³= 8+8 =16
pij ,p31= 4(3) +(1)³=12+1=13
pij ,p32= 4(3) +(2)³=12+8=20

a letra i representa a posicao referente a linha

e a letra j referente a coluna

[p11 p12]
[p21 p22]
[p31 p32]

sendo assim p=

[5 12]
[9 16]
[13 20]
