Question

Calcule o determinante da matriz abaixo: *​

Answer 1

Calcule o determinante da matriz abaixo:

$\Large\boxed{\begin{array}{l} \Large\boxed{\begin{array}{l} \sf\begin{pmatrix} \sqrt{2}&4 \\ - 3& - \sqrt{2} \end{pmatrix} \end{array}}\end{array}}$

Cálculos:

$\Large\boxed{\begin{array}{l} \Large\boxed{\begin{array}{l} \sf{det = \sqrt{2} } \times ( - \sqrt{2}) - 4 \times ( - 3) \\ \\ \sf{det = - 2 + 12} \\ \\ \boxed{ \boxed{ \boxed{ \boxed{ \sf{det = 10}}}}} \checkmark\end{array}} \end{array}}$
