Answer 1

Resposta:

$a) \left[\begin{array}{ccc}2&0&1\\4&1&3\\\end{array}\right]$     $b) \left[\begin{array}{ccc}0&2&-4\\-10&0&-12\\\end{array}\right]$   $c)= \left[\begin{array}{ccc}4&-1&4\\13&2&12\\\end{array}\right]$

Explicação passo-a-passo:

$a) 5. \left[\begin{array}{ccc}2&0&1\\4&1&3\\\end{array}\right]$ $= \left[\begin{array}{ccc}10&0&5\\20&1&15\\\end{array}\right]$

$b) -2. \left[\begin{array}{ccc}0&-1&2\\5&0&6\\\end{array}\right]$  $= \left[\begin{array}{ccc}0&2&-4\\-10&0&-12\\\end{array}\right]$

$c) 2. A =>2. \left[\begin{array}{ccc}2&0&1\\4&1&3\\\end{array}\right]$  $= \left[\begin{array}{ccc}4&0&2\\8&2&6\\\end{array}\right]$

$2A + B= \left[\begin{array}{ccc}4&0&2\\8&2&6\\\end{array}\right]$ $+ \left[\begin{array}{ccc}0&-1&2\\5&0&6\\\end{array}\right]$ $= \left[\begin{array}{ccc}4&-1&4\\13&2&12\\\end{array}\right]$
