Answer 1

Resposta:

Explicação passo a passo:

det A=

[(2.3.2)+(2.1.0)+(5.1.4)] -[(0.3.5)+(4.1.2)+(1.2.2)]=

[12+0+20]-[0+8+4]=

32-12=

20

Explicação passo-a-passo:

$\mathsf{A=\left[ \begin{array}{ccc}\sf2&\sf1&\sf0\\\sf2&\sf3&\sf4\\\sf5&\sf1&\sf2\end{array} \right]}$

$\mathsf{det\,A=\left|\begin{array}{ccc}\sf2&\sf1&\sf0\\\sf2&\sf3&\sf4\\\sf5&\sf1&\sf2\end{array}\right|\left|\begin{array}{cc}\sf 2&\sf1\\\sf2&\sf3\\\sf5&\sf1\end{array}\right|}$

$\mathsf{ det\,A= [12+20+0]-[0+ 8+4] }$

$\mathsf{ det\,A=[32+0]-[8+4] }$

$\mathsf{ det\,A=[32]-[12]}$

$\boxed{\boxed{\mathsf{ det\,A= 20}}}$
