The magnitude M of an earthquake is measured using the formula M=log(x/c), where x
is the measured amplitude of a seismic wave and c is the reference amplitude of one micron. Two earthquakes are measured. The amplitude of a seismic wave in the first earthquake is 40 times the amplitude of a seismic wave in the second earthquake. How much greater is the magnitude of the first earthquake than the second earthquake? Round your answer to the nearest hundredth.
The magnitude of the first earthquake is about (blank) units greater than the magnitude of the second earthquake.
