7. Verify the associative property of matrices

Answer variants:

$\left[\begin{array}{ll}47& 72\\ 33& 28\end{array}\right]$

$\left[\begin{array}{ll}382& 595\\ 248& 380\end{array}\right]$

$\left[\begin{array}{ll}382& 595\\ 248& 380\end{array}\right]$

$\left[\begin{array}{ll}26& 35\\ 36& 60\end{array}\right]$

Show that \(A(BC) = (AB)C\) if \(A =\begin{bmatrix}
5 & 7\\
4 & 4
\end{bmatrix}, B = \begin{bmatrix}
1 & 6\\
6 & 6
\end{bmatrix}, C = \begin {bmatrix}
2 & 5\\
4 & 5
\end{bmatrix}\)
