Scientists used a sample of spruce wood from some forest to date an advance of the continental ice sheet into some country during the last Ice Age. If 24.38% of the carbon-14 remains in the sample, when did the ice sheet advance? (Assume that this advance killed the tree.) The half-life of carbon-14 is 5730 years. ... The ice sheet advanced approximately years ago. (Round the base of the exponential function to six decimal places. Then round the final answer to the nearest year as needed.)
