**Inverse Matrix A ^{-1}**

AA^{-1} = I and A^{-1} A = I ?

A =

A^{-1} =

Note:- A^{-1} does not mean ; here , A^{-1} is just the notation for the multiplicative inverse of matrix A. Also, only square matrices can have inverses can have inverses because both A^{-1} A and AA^{-1} must exist and be equal to I.
