\(p = \begin{vmatrix} x & 3 & 0 \\ 2 & y & 3 \\ 4 & 2 & 4 \end{vmatrix}\)

\(q = \begin{vmatrix} x & 2 & z \\ 3 & y & 2 \\ 0 & 3 & z \end{vmatrix}\) Where \(p^T\) is the transpose p calculate \(/p^T/\) when x = 0, y = 1 and z = 2

 =  | 0 3 0 2 1 3 4 2 2 |
PT =  | 0 2 4 2 1 3 0 3 2 |
/pT/ =  | 0 2 4 3 1 3 0 3 2 |
= 0[2 - 6] - 2[6 - 0] + 4[9 - 0]
= 0 - 12 + 36 = 24
