Correct the wrong answer
In this question the matrices A, B, C, D and P are invertible matrices of the same size and s is a non-zero scalar. Simplify the following matrix expressions and match with the given choices In the exam you must be able to justify each step using the rules of matrix multiplication, transpose and the fact that A-1A = 1 and AA-1 = 1. (B 1A1) (AB) (CB1AT1) (ABC) (aA)(14-1 I (identity matrix) I (identity matrix) I (identity matrix) I (identity matrix) l (identity matrix) A)AT At(4-1) (P AP) (ABC)(CB A1) B(ATB)(BA)(ABAA (AC)(AC)(AC (AD) CD- (AB)(BA-+) I (identity matrix) | I (identity matrix) ? l (identity matrix) v |
