This topic focuses on simplifying radical expressions that involve division, specifically with integers divided by radicals where the radicand (the number under the radical sign) has a mixed index and is raised to a power. The exercises help strengthen skills in manipulating indices and simplifying expressions involving roots (square roots, cube roots, etc.). The problems present expressions in which an integer is divided by a radical, and students are tasked with determining what integer the expression simplifies to, choosing from several multiple-choice options.
