Resposta:

$\textsf{Segue a resposta abaixo}$

Explicação passo-a-passo:

$\left[ \begin{array}{ccc}\sf4&\sf6&\sf2\\\sf2&\sf4&\sf4\\\sf4&\sf1&\sf2\end{array} \right]$

$\sf det= \left| \begin{array}{ccc}\sf4&\sf6&\sf2\\\sf2&\sf4&\sf4\\\sf4&\sf1&\sf2\end{array} \right|\left|\begin{array}{cc}\sf4&\sf6\\\sf2&\sf4\\\sf4&\sf1\end{array}\right|$

$\mathsf{ det= [32+96+4]-[24+16+32] }$

$\mathsf{det= [128+4]-[40+32] }$

$\mathsf{det=[132]-[72] }$

$\boxed{\boxed{ \mathsf{ det=60}}}$
