To find the value of \( a \, \text{adj}(\text{adj} A) \) given that \( |A| = 2 \) and \( A \) is a square matrix of order 3, we can follow these steps: ### Step 1: Understand the properties of adjoint matrices The adjoint of a matrix \( A \), denoted as \( \text{adj} A \), has a property that relates it to the determinant of \( A \). Specifically, for a square matrix \( A \) of order \( n \): \[ \text{adj} A = |A|^{n-1} A^{-1} \] For a 3x3 matrix, this becomes: ...
