22. nth Roots of Unity Form an Abelian Group | Group Theory | B.Sc/M.Sc Maths

Welcome to Lecture 22 of our Group Theory series! In this highly focused session, we explore one of the most elegant examples in abstract algebra: the Set of nth Roots of Unity. We provide a step-by-step proof demonstrating that the set of all complex nth roots of unity forms a valid group under multiplication. We then go a step further to prove that this group is Abelian (commutative). This concept is fundamental for understanding cyclic groups, complex analysis, and number theory. This video is perfect for undergraduate mathematics students (B.Sc, M.Sc) and anyone preparing for competitive exams like JAM, GATE, or CSIR NET. 🔔 Subscribe for more lectures on Abstract Algebra! group theory, lecture 22, nth roots of unity, roots of unity, abelian group, commutative group, group theory proof, abstract algebra, complex numbers, de moivres theorem, cyclic group, un, set of roots of unity, forms a group, group theory examples, bsc maths, msc maths, jam maths, gate maths, csir net maths, algebra help, modern algebra, higher mathematics, what is roots of unity, group theory tutorial, mathematics lecture, complex analysis #GroupTheory #RootsOfUnity #AbstractAlgebra #AbelianGroup #Mathematics #ComplexNumbers #MathLecture #BScMaths #MScMaths #Algebra #DeMoivreTheorem #CyclicGroup
