Question

Evaluate the following determinants and negative of determinants of order two: 3459 and -3642

Solution

To evaluate the determinant of a 2x2 matrix, you use the formula ad - bc, where a, b, c, and d are the elements of the matrix.

However, the numbers you've provided (3459 and -3642) don't seem to correspond to a 2x2 matrix. A 2x2 matrix should have 4 elements. For example, a 2x2 matrix could look like this:

a b c d

If you could provide the four elements of your 2x2 matrices, I would be able to help you calculate the determinants.
