A now-archive but still brilliant resource: The (math.case.edu) attempted to solve every exercise in D&F before transitioning to other texts. Their solutions are conceptually clear but occasionally skip subtle induction steps.
And if you do find a complete, correct solution to Exercise 18.5.12? Please, for the love of Galois, put it on GitHub. But leave a comment warning about the subtle case. Someone will thank you ten years from now. solutions to abstract algebra dummit and foote
To the hungry student, these are gold. Problem 7.4.23? Solved. Problem 14.2.7? A terse but correct two-line proof. The downside: they assume a level of fluency that a struggling undergraduate may not have. A now-archive but still brilliant resource: The (math

Unlike undergraduate calculus texts, there is no official, publisher-sanctioned solution manual for Dummit & Foote. This is intentional. At the graduate level, the goal is to develop "mathematical maturity"—the ability to verify one's own logic. An official manual would potentially short-circuit the struggle necessary to master the material. Community-Driven Solutions
