Question

dada as matrizes ..... calcule o resultado da seguinte operação !!!!!​

Answer 1

Olá Viih, tudo bem?

Resposta:

$\left[\begin{array}{ccc}-1&1&-4\\-2&4&2\end{array}\right]$

Explicação passo-a-passo:

b)1/2 A =

$\left[\begin{array}{ccc}0&2&-1\\3&1&4\end{array}\right]$

agora vamos calcular 1/3B:

$\left[\begin{array}{ccc}-1&2&3\\4&-2&0\end{array}\right]$

Agora vamos calcular A - B - C

$\left[\begin{array}{ccc}0&2&-1\\3&1&4\end{array}\right]$ - $\left[\begin{array}{ccc}-1&2&3\\4&-2&0\end{array}\right]$ =

$\left[\begin{array}{ccc}-1&0&-4\\-1&3&4\end{array}\right]$

$\left[\begin{array}{ccc}-1&0&-4\\-1&3&4\end{array}\right]$ - $\left[\begin{array}{ccc}0&-1&0\\1&-1&2\end{array}\right]$ =

$\left[\begin{array}{ccc}-1&1&-4\\-2&4&2\end{array}\right]$

Espero ter ajudado, abraços e bons estudos!
