Use the formula : A=Iekt ( where A is the amount ofradioactive material remaining from an initial amount I, at a giventime, t and k is a negative constant determined by the particularnature of that material), to solve the following:
A certain radio isotope has a half-life of approximately 1,650years. How many years would be required for a given amoutn of thisisotope to decay to 65% of that amount?
PLEASE show me how to work this out?? THANKS!!
