Exponents - Negative Fractional Base (Level 2)

This math topic focuses on the application and understanding of exponents with negative fractional bases. The problems require calculating the results of negative fractions raised to positive exponents. Students are presented with various fractions like \(-\frac{2}{7}\), \(-\frac{7}{4}\), \(-\frac{7}{5}\), \(-\frac{8}{6}\), \(-\frac{2}{3}\), \(-\frac{6}{7}\), and \(-\frac{3}{7}\), all raised to certain powers, and they must determine the correct outcome from multiple choices provided for each question. This is designed to build proficiency in managing fractional bases with negative numbers in exponentiation scenarios.
