This math topic focuses on calculating ratios of measured values based on differences in logarithmic scales, particularly in contexts such as pH scales, decibel (dB) scales for sound, and the Richter scale for earthquakes. It explores how to determine the ratio of hydrogen ion concentrations in solutions of different pH levels, the ratio of sound energy between different decibel levels, and the ratio of seismic wave sizes from earthquakes of varying magnitudes on the Richter scale. Each problem is presented with multiple-choice answers and involves applying logarithmic functions to find the correct ratios.
