Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C has decayed to 1/16.0 of the original amount. How long ago was this plant alive?

The question is asking to determine and calculate the duration or year that the plants was alive, base on the data that is represented in the problem, by my computation and further research, I would say that the plants is 2.29*10^4 years ago that the plants is alive. I hope you are satisfied with my answer and feel free to ask for more
