What is Homework Solutions: Subrings & Zero Divisors about?
The document provides solutions to homework problems involving rings, fields, and other abstract algebra concepts. Specifically: - Problem 18 on page 241 shows that the set S = {x ∈ R | ax = 0} is a subring of R by verifying it satisfies the subring test. - Problem 42 on page 243 shows that the set of 2x2 matrices over Z with integer entries is a subring of M2(Z). - Problem 36 on page 256 proves that Zp[√k] is a field if and only if the equation x2 = k has no solutions in Zp.
