R=log(I/Io)
R is the Richter number of the earthquake, I is the intensity of the earthquake, and Io is the intensity of the minimum detectable earthquake.
Please help! An earthquake has a Richter number of 4.2. How many times more intense than the minimum detectable earthquake is the earthquake? Round your answer to the nearest whole number
