1.-Let p a prime and let , (this is a extension field) , where is an irreducible polynomial over . Show that if are elements of that satisfy .

Note this show that the pth powers of the elements of are distinct, and therefore every element in is the pth power of a unique element in . Therefore every element in has a unique pth root; that is, for any in there is a unique in such that . This property is not true for the field of real numbers since .

Please, can you explain with details this problem by step by step?

Remember that: Let a and b be indeterminants over the field , where p is prime then
