Q: Berechne \(A^{-1}\) für:

\(A =\begin{pmatrix}
1&2  \\
3&5
\end{pmatrix}\)
- \begin{pmatrix}-5& 2 \\ 3 & -1\end{pmatrix} (correct)
- \begin{pmatrix}2 & -5 \\ -1 & 3\end{pmatrix} (\(A^{-1}=\frac{1}{det(A)}\begin{pmatrix}d & -b \\-c & a\end{pmatrix}\))
- \begin{pmatrix}5 & 2 \\ 1 & 1\end{pmatrix} (\(A^{-1}=\frac{1}{det(A)}\begin{pmatrix}d & -b \\-c & a\end{pmatrix}\))
