2. The relation between the magnitude M of an earthquake and the amplitude A units of the seismic wave measured can be represented by the following formula: M = log A + K, where K is a constant. In a city, the amplitudes recorded in the first and the second earthquakes were 50 units and 750 units respectively. What was the difference in the magnitudes of the two earthquakes? (Give the answer correct to 2 decimal places.)
