This math topic focuses on solving exponential equations using the power law, particularly when a constant base is raised to a variable power (x). The problems explore equalities such as 3^x = 9^2, 2^x = 4^26, and similar expressions. Each question provides six potential values of x as multiple-choice answers. The overall aim is to consolidate an understanding of exponents, including negative and fractional exponents, through solving for the variable x in various exponential settings. This theme is embedded in a broader study unit on exponents.
