[2 3 5] is determinate A = |A |= [235] which has value of 45 .. find the miner of the following elements

Question

1. 2
2. 3
3. 5

Answer 1

The minors of the elements in the matrix A = [2 3 5] are:

1. The minor of 2 is obtained by removing the row and column containing 2 from the matrix A. Since there is only one row and one column left, the minor of 2 is simply the determinant of the remaining matrix, which is 1.

2. The minor of 3 is obtained by removing the row and column containing 3 from the matrix A. Again, since there is only one row and one column left, the minor of 3 is simply the determinant of the remaining matrix, which is 1.

3. The minor of 5 is obtained by removing the row and column containing 5 from the matrix A. Once again, since there is only one row and one column left, the minor of 5 is simply the determinant of the remaining matrix, which is 1.
