This problem is driving me crazy! Please help.
The half-life of an element is 4.3 x 10^9 yr. How long does it take a sample of the element to decay to 3/5 of its original mass? Use A=Ao(1/2)^(t/T) where Ao is the initial amount, T is the half-life, and t is the time. (Express results in scientific notation, rounded to the nearest hundredth.)
Thanks,
Diane
