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


sendo bij = 3i - j²

b11 = 3.1 - 1² = 3- 1 = 2
b12 = 3.1 - 2² = 3 - 4 = -1
b21 = 3.2 - 1² = 6 - 1 = 5
b22 = 3.2 - 2² = 6 - 4 = 2
b31 = 3.3 - 1² = 9 - 1 = 8
b32 = 3.3 - 2² = 9 - 4 = 5

matriz : 

  \left[\begin{array}{ccc}2&-1&\\5&2&\\8&5&\end{array}\right]

o elemento b22 = 2
