The following exercise poses a question that can be answered by solving an equation. Give the appropriate equation. Note that you are not asked to solve the equation. Argon-39 is a radioactive isotope of argon. Initially a sample of argon-39 contains 12 grams, and the amount remaining after t years is given by A = 12 x 0.5t/269 grams. The half-life is the time required for the amount of argon-39 to be reduced by half. The half-life of argon-39 is the solution of an equation. Find that equation.
