Guided Proof Let B be an invertible n n matrix. Prove that the linear transformation T: Mn,nMn,n represented by T(A) = AB is an isomorphism. Getting Started: To show that the linear transformation is an isomorphism, you need to show that T is both onto and one-to-one. (i) T is a linear transformation with vector spaces of equal dimension, so by Theorem 6.8, you only need to show that T is one-to-one. (ii) To show that T is one-to-one, you need to determine the kernel of T and show that it is {0} (Theorem 6.6). Use the fact that B is an invertible n n matrix and that T(A) = AB. (iii) Conclude that T is an isomorphism.

Let B be an invertible n × n matrix. Prove that the linear transformation \(T: M_{n,n} \rightarrow M_{n,n}\) represented by T(A) = AB is an isomorphism. Getting Started: To show that the linear transformation is an isomorphism, you need to show that T is both onto and one-to-one. (i) T is a linear transformation with vector spaces of equal dimension, so by Theorem 6.8, you only need to show that T is one-to-one. (ii) To show that T is one-to-one, you need to determine the kernel of T and show that it is {0} (Theorem 6.6). Use the fact that B is an invertible n × n matrix and that T(A) = AB. (iii) Conclude that T is an isomorphism. Text Transcription: T: M_n,n rightarrow M_n,n
