Text Solution

AI Generated Solution

To find the minors and cofactors of the elements of the given determinants, we will follow a systematic approach. Let's solve each determinant step by step. ### (i) Determinant: `|(2, -4), (0, 3)|` 1. **Identify the elements of the determinant**: - The elements are: - \( a_{11} = 2 \) - \( a_{12} = -4 \) ...
