1. Matriks A = ![\left[\begin{array}{ccc}3&-4\\2&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-4%5C%5C2%261%5Cend%7Barray%7D%5Cright%5D "\left[\begin{array}{ccc}3&-4\\2&1\end{array}\right]")
B = ![\left[\begin{array}{ccc}-3&-2\\-1&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%26-2%5C%5C-1%265%5Cend%7Barray%7D%5Cright%5D "\left[\begin{array}{ccc}-3&-2\\-1&5\end{array}\right]")
C = ![\left[\begin{array}{ccc}5&4\\-2&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%264%5C%5C-2%26-1%5Cend%7Barray%7D%5Cright%5D "\left[\begin{array}{ccc}5&4\\-2&-1\end{array}\right]")
