Question

prove that inverse of a matrix , if exists, is unique.​

Answer 1

Step-by-step explanation:

Properties of the Matrix Inverse. The next theorem shows that the inverse of a matrix must be unique (when it exists). (Uniqueness of Inverse Matrix) If B and C are both inverses of an n × n matrix A, then B = C. B =B In = B(A C) = (B A)C =InC = C.
