# Carbon dating logarithmic

He knows that he needs to use an exponential to do this. So if I plug in the percent carbon that I have on the left-hand side, I can solve this equation for the age of my material.

He has y = a^x, where a is a base and x is the exponent. Say that there's 30% of this special carbon in our math book.

Much of the power of logarithms is their usefulness in solving exponential equations.

Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (p H balance, a measure of acidity and alkalinity).

Free 5-day trial Let's return to a scientist studying an old math book. If I divide both the left and right side by 5730, I can calculate C. Anyone can earn credit-by-exam regardless of age or education level.

Let's go through some properties of e and the natural log. To solve for C, I need to first take the natural log of both the left-hand side and the right-hand side. If I use my property that ln(e^x) = x, the right-hand side is equal to 5730C. You can test out of the first two years of college and save thousands off your degree.Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.Solution Since 40% of Carbon-14 is lost, 60% is remained, or 0.6 of its initial amount. Thus, you should solve an equation C(t)=0.6, which is , for unknown t.

Yet on a social occasion you will often find that the Burmese women cluster together on one side of the room and leave their men to talk to each other in a group of their own.
