Let R be the ring of Gaussian integers: R= {m+ni | m, ne z} where i = √-1. Set I=5R, the principal ideal of R generated by 5. Do the one statement below about the factor ring R/I which is true: (a) Every nonzero element of R/I is a unit (in other words, R/I is a field). Pair off each nonzero element with its inverse. of (b) Nonzero elements of R/I exist which are zero divisors. Find one. Let R be the ring of Gaussian integers: R= {m+ni | m, ne z} where i = √-1.
