This math topic focuses on practicing calculations with negative exponents. It includes a series of problems where numbers are raised to negative powers, such as \(9^{-2}\), \(10^{-2}\), and others up to \(4^{-2}\). Each problem presents a base number to be raised to a negative exponent and multiple answer choices, each given as fractions. The objective is to select the correct fraction that represents the value of the expression with the negative exponent.
