"WebWe will raise that by the number of years divided by the number of years in the half-life. In this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444. " - How to do half life in chemistry
