If A and B are 3 × 3 real matrices such that rank(AB) = 1, then rank(BA) cannot be
Question
Solution 1
The rank of a product of two matrices is less than or equal to the minimum rank of the two matrices. Therefore, if rank(AB) = 1, then rank(BA) cannot be more than 1. However, it's important to note that the ranks of AB and BA are not necessarily equal, so rank(BA) could also be 0.
