Roots of complex numbers and regular polygons

Explore all nth roots of complex numbers through exact algebra, polar angles and regular-polygon geometry. This precalculus practice set builds from counting roots and finding their radius to complete solution sets, geometric interpretation and error analysis. Single-select and multiselect questions distinguish a principal root from every root and address the exceptional zero case. Detailed solutions check completeness, angle spacing and direct substitution. Use the coordinate diagram to connect a plotted configuration with a polynomial equation.
