−−−=10λλλln.RNRNtWe solve for N: NRNRet=+ −FHIK−λλλ0. After many half-lives, the exponential is small and the second term can be neglected. Then, N = R/λ, regardless of the initial value N0. At times that are long compared to the half-life, the rate of production equals the rate of decay and Nis a constant. 43. If Nis the number of undecayed nuclei present at time
