The magnitude of an earthquake is given by the Richter scale, whose formula is R = log - where I is the intensity of the earthquake and I, is the intensity of a minimal earthquake and used for comparison purposes. The 1906 city A earthquake had a magnitude of 8.07, and the 1964 city B earthquake had a magnitude of
6.8. Compare the intensities of the two earthquakes.
The 1906 city A earthquake was approximately times more intense than the 1964 city earthquake.
