Suppose that you trying to determine the age of a particular rock. The rock contains a form of potassium that radioactively decays into argon, with a half-life for this process of 1.3 billion yrs. If 3/4 of the potassium that was initially present has decayed, how many years ago did this rock form? [Enter your answer in years as a large integer or in scientific notation, i.e., as 4.6е+7]
