Question

If A is a non singular matrix then A inverse is​

Answer 1

Answer:

A inverse is B

Step-by-step explanation:

* 'A' is non- singular matrix, if another matrix is 'B' which of the same order than AB=BA=I . where 'I' is the unit Matrix and 'B' is called inverse of 'A'.

[•B= A-1]

* Inverse of matrix square Matrix 'A' exist only if 'A' is non-singular Matrix.

* Inverse of a square Matrix is always unique.

* Formula:- A-1=Adj A/ |A|
