Answer:
Step-by-step explanation:
hello,
i advice you check the question again if it is GF() or GF(24). i believe the question should rather be in this form;
multiplication in GF(): Compute A(x)B(x) mod P(x) =
+
+1, where A(x)=
+1, and B(x)=
.
i will solve the above question and i believe with this you will be able to solve any related problem.
A(x)B(x)=
=
=
please note that the division by the modulus above we used
