Understanding Radioactive Decay and Half-Life

This video tutorial explains how to calculate the decay time of radioactive substances using the half-life model. It covers solving exponential equations with logarithms, compares exponential decay to compound interest, and provides examples of calculating half-life, including a detailed example with plutonium. The tutorial emphasizes the importance of understanding inverse operations and the use of logarithms in solving these problems.
