The document discusses how to solve exponential equations. It provides examples of solving equations involving exponential expressions like 3x = 27, 4x = 8, and 15x = 295. It also gives two word problems about folding paper and rabbit populations that can be modeled with exponential equations and asks the reader to determine the number of folds or years to reach a given thickness or population.
