A=[010030101].arrow_forwardDetermine subspaces of Mn,n In Exercises 2936, determine whether the subsetMn,n is a subspace ofMn,nwith the standard operations. Justify your answer. The set of all nn diagonal matricesarrow_forward
- In general, it is difficult to show that two matrices are similar. However, if two similar matrices are diagonalizable, the task becomes easier. In Exercises 38-41, show that A and B are similar by showing that they are similar to the same diagonal matrix. Then find an invertible matrix P such that .arrow_forwardDetermine Whether Two Matrices Are Similar In Exercises 21-24, determine whether the matrices are similar. If they are, find a matrix P such that A=P1BP. A=[5003],B=[7241]arrow_forwardLet A and B be square matrices of order n satisfying, Ax=Bx for all x in all Rn. a Find the rank and nullity of AB. b Show that matrices A and B must be identical.arrow_forward
