Question

How do you find the inverse of `A=``((11, 12), (13, 14), (15, 16))`?

Answer 1

Please see below.

Explanation:

Here,

`A=((11,12),(13,14),(15,16))`

It is clear that `A` is `3xx2` matrix.

So , `A` is not a square matrix .

The condition for any matrix `A` has an inverse matrix is that
`A` must square matrix.

So , inverse matrix of `A` does not exist . In the other words `A^-1` is not defined.
