Solve the Problem $M _ { L }$ (On the Richter Scale) of an Earthquake of Intensity

Multiple Choice

Solve the problem.
-The local magnitude $M _ { L }$ (on the Richter scale) of an earthquake of intensity $I$ is given by $M _ { L } = \log \left( \frac { I } { I _ { 0 } } \right)$ where $I _ { 0 }$ is a minimum reference intensity of a "zero-level" earthquake against which the intensities of other earthquakes may be compared. How many times more intense is an earthquake of magnitude $5.8$ than an earthquake of magnitude $2.9$ ? Round to the nearest whole number.

A) Approximately 2 times more intense.
B) Approximately 794 times more intense.
C) Approximately 481 times more intense.
D) Approximately 18 times more intense.
