Show that the ring (Z4, +4, cdot4) is an integral domain.
Show that the ring $(Z_4, +_4, \cdot_4)$ is an integral domain. [5]
The question asks to "show" that Z₄ is an integral domain, but the correct mathematical result is that (Z₄, +₄, ×₄) is NOT an integral domain. A well-prepared exam answer must demonstrate this with proof. (This is standard algebra; the question likely intends for students to test the definition a...
