This math topic focuses on simplifying radicals where the radicand involves division of an integer by a fraction, aiming to determine what integer the radical expression simplifies to. It covers exercises that require dividing numbers within a square root and then simplifying the expression to its simplest integer form. Each question provides a set of possible answers, from which the correct integer value that the radical simplifies to must be selected. This type of exercise is a key part of developing skills in algebraic manipulation and understanding the properties of radicals.
