3 determine a matriz transporta

4) Calcule o determinante da matriz A


​

Answer 1

3)

$A=\begin{vmatrix}3&-3&2\\1&7&2\\0&6&8\end{vmatrix}\\A^T=\begin{vmatrix}3&1&0\\-3&7&6\\2&2&8 \end{vmatrix}$

4)

$A=\begin{vmatrix}3&-3&2\\1&7&2\\0&6&8\end{vmatrix}\\\mathsf{det~A=3(56-12)+3.8+2.6}\\\mathsf{det~A=132+24+12}$

$\boxed{\boxed{\boxed{\boxed{\mathsf{det~A=168}}}}}$
