The exponential decay function A = A0(1/2)^t/P can be used to determine the amount A, of a radioactive substance present at time t, if A0 represents the initial amount and P represents the half-life of the substance. If a substance loses 70% of its radioactivity in 500 days, determine the period of the half-life.
