Common Logarithm. How many fingers do we (normally) have?. What happens after the number 9?. What happens after the number 99?. Why is it easier to multiply by 100 that by 99 even though 99 is a smaller number?. The derailment on October 22, 1895 of the Granville-Paris Express that overran the buffer stop. The engine careened across almost 100 feet (30 meters) of the station concourse, crashed through a two-foot thick wall, shot across a terrace and sailed out of the station, plummeting onto the Place de Rennes 30 feet (10 meters) below where it stood on its nose. While all of the passengers on board the train survived, one woman on the street below was killed . Section 6.5 Beginning on page 327. Properties. Because logarithms are the inverse functions of the exponential functions, properties of logarithms are similar to properties of exponents. . Product Property:. Logarithms. Logarithms with base 10 are common logs. You do not need to write the 10 it is understood. Button on calculator for common logs. LOG. Examples: Use calculator to evaluate each log to four decimal places.
