The Richter scale is a numerical scale that uses base 10 logarithms

The Richter scale is a numerical scale that uses base 10 logarithms for measuring an earthquake's magnitude. The larger the number, the more intense the earthquake. For example, an earthquake with a magnitude of 5.0 is 10 times more intense than an earthquake with a magnitude of 4:0. Two well-known earthquakes occurred in the year 1906. The San Francisco earthquake had a magnitude of 7.9, and the Chile earthquake had a magnitude of 8.2. Approximately how many times more intense was the Chile earthquake than the San Francisco earthquake? A 0.3 B 0.5 C 2.0 D 3.0
