Question

Alguém pode me ajudar nessa questão sobre matriz?

Answer 1

Resposta:

$\left[\begin{array}{ccc}0&2&\\\frac{1}{2} &0\end{array}\right] . \left[\begin{array}{ccc}0&2&\\\frac{1}{2} &0\end{array}\right]=\left[\begin{array}{ccc}1&0&\\0 &1\end{array}\right]$

$\left[\begin{array}{ccc}0&2&\\\frac{1}{2} &0\end{array}\right].\left[\begin{array}{ccc}0&2&\\\frac{1}{2} &0\end{array}\right].\left[\begin{array}{ccc}0&2&\\\frac{1}{2} \\\\&0\end{array}\right]=\left[\begin{array}{ccc}1&0&\\0 &1\end{array}\right].\left[\begin{array}{ccc}0&2&\\\frac{1}{2} &0\end{array}\right] =\\\left[\begin{array}{ccc}0&2&\\\frac{1}{2} &0\end{array}\right]$

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