Log half life formula

WitrynaOne of the common terms associated with exponential decay, as stated above, is half-life, the length of time it takes an exponentially decaying quantity to decrease to half its original amount. Every radioactive isotope has a half-life, and the process describing the exponential decay of an isotope is called radioactive decay. WitrynaOkay, so we will to find ah rate of the K K. Given that are half life is eight days sore. H really is eight. So let's solve the fallen for K. So let's take base kind to both sides. So …
