This topic focuses on the skills of multiplying monomials involving radicals over unit fractions. It includes simplifying radical expressions after multiplication and dealing with operations against fractional denominators. The problems require students to simplify square roots and adjust their calculations with division by unit fractions (like 1/2, 1/3, 1/4, 1/5), fostering an understanding of both radical operations and the effects of dividing by fractions in algebraic contexts. Each problem provides several answer choices, emphasizing solution verification and the consolidation of multiplying and simplifying operations with radicals.
