A and B are two non−singular matrices  such that A^6 =I and AB^2 =BA(B≠I).  Then value of K for which B^K =I.
$${A}\:{and}\:{B}\:{are}\:{two}\:{non}−{singular}\:{matrices} \\ $$$${such}\:{that}\:{A}^{\mathrm{6}} ={I}\:{and}\:{AB}^{\mathrm{2}} ={BA}\left({B}\neq{I}\right). \\ $$$${Then}\:{value}\:{of}\:{K}\:{for}\:{which}\:{B}^{{K}} ={I}. \\ $$
