​Carbon-14 (14C)dating assumes that the carbon on the Earth today has the same radioactive content as it did centuries ago.If this is true,then the amount of 14C absorbed by a tree that grew several centuries ago should be the same as the amount of 14C absorbed by a similar tree today.A piece of ancient charcoal contains only 24% as much of the radioactive carbon as a piece of modern charcoal.How long ago was the tree burned to make the ancient charcoal? (The half-life of 14C is 5715 years.)Round your answer to the nearest integer. ​
