چکیده
|
Unlike the real number field r,a bi-quadratic equation x4 + 1 = 0 is solvable over some p-adic number fields qp,say p = 17,41,· · ·. therefore,it is of independent interest to provide a solvability criterion for the bi-quadratic equation over p-adic number fields qp. in this paper,we provide solvability criteria for the bi-quadratic equation x4 + ax2 = b over domains z*p,zp z*p,zp zp,qp,where p > 2. moreover,we also provide the number of roots of the bi-quadratic equation over the mentioned domains.
