Question

Which statement is true about the determinant of a matrix? The determinant of a singular matrix is equal to zero. The determinant of an inverse matrix is equal to zero. The determinant of an identity matrix is equal to zero. The determinant of a zero matrix is equal to one.

Answer 1

A determinant is a quantity that is obtained by the addition of products of the elements of a square matrix according to a given rule. The true statement about the determinants from the given choices is that:
The determinant of a singular matrix is equal to zero.

It's good to note that the determinant of an identity matrix is 1 NOT 0
