"WebConsider n = 25. Following the above procedure, we first find a primtive 5th root of unity. We might find the 5th primitive root: α = − 1 − 5 4 − i 5 − 5 8. We next take a 5th root of α to obtain a primitive 25th root of unity. However, a radical that only works on reals means we cannot simply write α 5. " - Primitive root of 11
