The Determinant of the Inverse of a Matrix In Exercises 2530, find A1 . Begin by finding

Chapter 3, Problem 25

(choose chapter or problem)

In Exercises 25–30, find \(\left|A^{-1}\right|\). Begin by finding \(A^{-1}\), and then evaluate its determinant. Verify your result by finding |A| and then applying the formula from Theorem 3.8, \(\left|A^{-1}\right|=\frac{1}{|A|}\).

\(A=\left[\begin{array}{ll}

2 & 3 \\

1 & 4

\end{array}\right]\)

Text Transcription:

|A^-1|

A^-1

|A^-1|=1/|A|

A=[2 & 3
