Inverse Matrix A-1

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.
