Some help I have gotten so far but still don't know how to proceed from there:

To prove that the geometric multiplicities of the eigenvalues of A and B are the same, we can show that, if B = P^-1 AP , then every eigenvector of B is of the form P^-1 v for some eigenvector v of A.

And i also know that for A and B to be similar matrices, these 5 properties must hold.

1. det A = det B

2. A and B have the same rank

3. A and B have the same characteristic polynomial

4. A and B have the same eigenvalues

5. A is invertible iff B is invertible

any help would be greatly appreciated
