A - B

• Veja o Cálculo:

$\large \sf \begin{bmatrix}\large \sf-3&\large \sf5&\large \sf2\\\large \sf6&\large \sf4&\large \sf8\\\end{bmatrix}\large \sf-\begin{bmatrix}\large \sf-8&\large \sf-9&\large \sf12\\\large \sf45&\large \sf6&\large \sf-3\\\end{bmatrix}\\\\\\\large \sf \begin{bmatrix}\large \sf-3-(-8)&\large \sf\:\:5-(-9)&\large \sf\:\:2-12\\\large \sf6-45&\large \sf\:\:4-6&\large \sf\:\:8-(-3)\\\end{bmatrix}\\\\\\\large \sf\begin{bmatrix}\large \sf5&\large \sf14&\ \sf-10\\\large \sf-39&\sf -2&\sf 11\\\end{bmatrix}$
