answer it by the MATLAB
The magnitude, M, of an earthquake on the Richter scale is given by: M = 2/3 log E/E_0 where E is the energy released by the earthquake, and the constant, E_0 =10^4.4 Joules, is the energy of a small reference earthquake. Determine how many times more energy is released from an earthquake that registers 7.2 on the Richter scale than an earthquake that registers 5.3.
