This math topic focuses on complex numbers, specifically how to rewrite roots of negative numbers as complex numbers and simplifying radicals. It explores the application of the fundamental theorem of algebra where each question provides a negative radicand, challenging students to express it in terms of an imaginary unit 'i' by simplifying square roots. This skill is essential in understanding the properties and operations involving complex numbers. The exercises require converting square roots of negative integers into their simplest imaginary form.
