Suppose $A$ and $B$ are two non singular matrices such that $AB= BA^2$ and $B^5=I$ (where $I$ is the identity matrix). If $A^k=I$, find the minimum positive value of $k$.

Hello student,
Please find my response to your question below
I think some part of question is missing over here,so iam unable to understand the question completely.
As you are asking minimum positive value of k
IsAsupposed to satisfy this for every possibleBwith B5=I?
because if k=1 then A=I and it satisfies your equation.
