Matriz genérica : 

  \left[\begin{array}{ccc}b11&b12&b13\\b21&b22&b23\\b31&b32&b33\end{array}\right]

construindo a matriz : 

bij = (i+j)³
b11 = (1+1)³ = 2³ = 8
b12 = (1+2)³ = 3³ = 27
b13 = (1+3)³ = 4³ = 64
b21 = (2+1)³ = 3³ = 27
b22 = (2+2)³ = 4³ = 64
b23 = (2+3)³ = 5³ = 125
b31 = (3+1)³ = 4³ = 64
b32 = (3+2)³ = 5³ = 125
b33 = (3+3)³ = 6³ = 216

matriz  :

  \left[\begin{array}{ccc}8&27&64\\27&64&125\\64&125&216\end{array}\right]
