Now, conveniently, there’s an equation we can use to relate the ratio of carbon 14 to carbon 12, to the time that has passed. That equation is this, R equals 10 to the negative 12, times e to the negative t over 8223. In this equation, R is that carbon 14 to carbon 12 ratio. And t is the age of the material we’re looking at measured in years. Now you just found that R for the parchment is 0.795 times 10 to the negative 12. So using this equation, how old is the parchment? Please round to the nearest year. Think about the techniques you know using logs to simplify and then solve this equation.
