一道关于碳14半衰期的问题,
Living matter has a carbon-14 activity of about 16.0counts/min per gram of carbon.What is the age of an artifact for which the carbon-14 activity is 8.00counts/min per gram of carbon?The half-life of carbon-14 is 5730 years.
主要试问当Carbon-14 活性为 8.00counts/min per gram of carbon,它的年龄是多少?
看得懂的帮忙回答一下,我不太确定怎么翻译成中文来问.不好意思,麻烦大家了.
还有能否告诉我怎么算的

翻译：有生命的物质的碳14 的活性是大约16.0 次/分钟/克.如果一件古迹的碳14 的活性是8.0 次/分钟/克,它的年龄是多少.碳14的半衰期是5730年.
答案：那件古迹的年龄是5730年.
算法：
8=16×(1/2)^(t/5730) ^是指数
8/16 = (1/2)^(t/5730)
(1/2)^1 = (1/2)^(t/5730)
1 = t/5730
