This math topic focuses on simplifying radicals, specifically involving the division of two terms over one term with a common radical factor, and then expressing the result as a fraction. Each problem presents a radical expression in the form of a fraction, where the numerator contains two terms (each under a radical), and the denominator contains one term under a radical. The exercises involve identifying the correct simplified form from multiple choices provided. These problems help enhance skills in manipulating and simplifying expressions involving square roots, a crucial aspect of algebra.
