The previous part could be done without using the decay equation, because the ratio of original 14c to present 14c was an integer power of 1/2. most problems are not so simple. to solve more general carbon-dating problems, you must first find the value of the decay constant for 14c, so that you can easily use the decay equation. using the given half-life, 5730 years, find the value of the decay constant for 14c.
