Question
Exercise 1 (On Similarity). Answer True or False.
i) If A, B € Mnxn are similar then A² and B² are similar.
ii) If A, B E Mnxn are similar then they have the same eigenvectors.
iii) If A is an eigenvalue of A and A is invertible then A-' is an eigenvalue of A-!.
iv) If A1, B1 are similar and A2, B2 are similar with A1, B1, A2, B2 € Maxn then A1 + A2
is similar to B1 + B2.
v) If A, B € Mnxn are similar then A' and B' are also similar.
