Abstract: Abstract Let l be an odd rational prime number and k(ζ) the cyclotomic field generated by ζ = e 2πi/l . Let μ be an integer of k(ζ) which is not the l-th power of a number in k(ζ); then the l-th degree equation $${x^l} - \mu = 0$$ is irreducible over the field k(ζ). If we choose a fixed root $${\text{M = }}\root l \of \mu $$ of this equation then the remaining l — 1 roots are $$\zeta M,{\zeta ^2}M,...,{\zeta ^{l - 1}}M.$$
