Chapter 3, Problem 55(choose chapter or problem)
In Exercises 51–56, use a software program or a graphing utility to find (a) |A|, (b) \(\left|A^{T}\right|\), (c) \(\left|A^{2}\right|\), (d) |2A|, and (e) \(\left|A^{-1}\right|\).
\(A=\left[\begin{array}{rrrr}
4 & -2 & 1 & 5 \\
3 & 8 & 2 & -1 \\
6 & 8 & 9 & 2 \\
2 & 3 & -1 & 0
\end{array}\right]\)
