Formula: Radioactive Decay Formula
  
Given: There are 13 grams of Plutonium-240.
Plutonium-240 has a half-life of 6,563 years.
  
Find:  Use the formula above to calculate the time it would take for the given mass to degrade down to 0.13 grams. Calculate the solution for 't' to the nearest tenth using logarithms.
  
Solution:   t = years
