Question

If A is a square n times n matrix, what is its inverse matrix?

Answer 1

The inverse matrix of a square matrix A is denoted as A^-1 and it satisfies the property AA^-1 = I. To find the inverse of a square matrix A, you can use methods such as Gauss-Jordan elimination or the matrix of cofactors.

Step-by-step explanation:

When a square matrix A is invertible, its inverse matrix is denoted as A-1. The inverse matrix A-1 satisfies the property that when multiplied with A, the result is the identity matrix I. In other words, AA-1 = I. To find the inverse of a square matrix A, you can use various methods such as the Gauss-Jordan elimination method or the matrix of cofactors method.
