Negative Fractional Exponents with Integer Base - Explanation to Answer (Level 1)

This math topic focuses on practicing how to handle negative fractional exponents with integer bases. Specifically, students interpret expressions like \( a^{-\frac{1}{2}} \times a^{-\frac{1}{2}} = \frac{1}{a} \), where 'a' is an integer, and determine the equivalent expression of a single exponent term. The exercises include identifying correct expressions among multiple choices for integer bases such as 36, 4, 9, 25, and 16 in relation to their negative fractional powers. This teaches the students about reciprocal and root operations with negative exponents in a simplified and concept-reinforcing manner.
