Exponents - Negative One Exponents with Unit Fractional Base (Level 2)

This math topic focuses on evaluating expressions with unit fractional bases raised to the power of negative one. Each problem presents a fraction with a denominator ranging from 2 to 11, raised to the exponent of -1. The learners are required to apply knowledge of exponents and fractions to simplify these expressions. Multiple choice answers accompanying each problem propose various simplifications, including integer, fractional, undefined (division by zero), and incorrect negative values, challenging the learner to correctly apply exponent rules and fraction reciprocation.
