K ln 62. We can now put k ln 62 into our formula from before. Decay constant lambda gives the ratio of number of radioactive atoms decayed to the initial number of atoms which is LARGE lambdafrac0693t_frac12 Decay Law is used to find the decay rate of a radioactive element.
To find the half-life of a function describing exponential decay solve the following equation.
Life of about 5730 years. We could calculate k 0896 but it is best to keep it as k ln 62 until we do our final calculations. This is exactly the type of relationship we want to describe half-life. We can now put k ln 62 into our formula from before.
