Practice: Using Negative Exponents with GeoGebra

This GeoGebra practice illustrates how negative exponents (a^{-n}) relate to reciprocal forms and how algebraic transformations can be represented and checked through constructed geometric elements. The example focuses on the definition a^{-n}=1/a^{n}, simplification of exponential expressions, and using visualization to build intuition for rewriting and verifying exponent rules. Construction-wise, it relies on the key GeoGebra objects listed in the provided construct summary—A1, B1, A2, A3, A4, A5—typically used as anchor points or intermediate points whose relationships (e.g., measured values or linked annotations) reflect the algebraic quantities under study. It is suitable for upper secondary and early university students, as well as for classroom demonstrations and self-study where learners benefit from connecting symbolic exponent rules to a concrete, visual representation.
