Question

.mais m rİaj modulo m(x). Exercise 14.14. Let us consider some simple examples of rings of congruence classes. 1. Show that there are four congruence classes in F2] modulo z2. Make addition and multiplication tables for the ring F2T22. Using the tables determine the units in the ring. Is F2]22 a field? 2. Show that the ring F can be identified with the field F itself. 3. Show further that we can identify Flalme) with F for any first-degree polynomial m(x) in F[x]

Answer 1

"Given collection from the data let us assume that the equations are we have to consider that the data is they are ring of congruences classes of those simples It is the four congruence classes are F_2
