Prove that if is any ideal of then is a multiple of the characteristic of.Let R be as in Exercise 1, and show that the principal ideal I=(2)={2n+m2|n,m} is a maximal ideal of R. Exercise 1. According to part a of Example 3 in Section 5.1, the set R={m+n2|m,n} is a ring. Assume that the set I={a+b2|aE,bE} is an ideal of R, and show that I is not a maximal ideal of R.Let R be a commutative ring that does not have a unity. For a fixed aR, prove that the set (a)={na+ra|n,rR} is an ideal of R that contains the element a. (This ideal is called the principal ideal of R that is generated by a. )
