Answer:

mark as brainlest

Step-by-step explanation:

In linear algebra, the determinant is a scalar value that can be computed from the elements of a square matrix, and which encodes certain properties of the linear transformation described by the matrix. The determinant of a matrix A is denoted det, det A, or |A|.

Answer 2

Answer:

A matrix is an array of many numbers. For a square matrix, i.e., a matrix with the same number of rows and columns, one can capture important information about the matrix in a just single number, called the determinant. The determinant of a 1×1 matrix is that number itself. ...

Step-by-step explanation:

For a 3×3 Matrix

The determinant is: |A| = a (ei − fh) − b (di − fg) + c (dh − eg). The determinant of A equals 'a times e x i minus f x h minus b times d x i minus f x g plus c times d x h minus e x g'.
