heres the question, A mummified human body was recently found in a Scandinavian bog. Radioactive carbon was used to find the age of the mummy.
The amount of carbon-14 had decayed to 4^-1/3 of its original amount. The half life of carbon-14 is about 5370 years. For how long has the mummy been dead?
I know you use y=ab^x but i dont know how u use it for this question.
