True or False? Justify your answer. a) Let A, B, and C be two square matrices of the same dimension and A be an invertible matrix then ((A^−1)BCA)^2023 = A^(−1)xB^(2023)xC^(2023)xA. b) Let A be an n×n matrix. The set of all n×n matrices X that satisfies (A^2 −3I)X = O is not be closed under the matrix addition. (O denotes the zero matrix of the proper dimensions.) c) If A and B are 6×6 matrices of rank 6, then AB also has rank 6.
