Solve the problem.The Richter scale magnitude R of an earthquake is based on the features of the associated seismic wave and is measured by R = log (a/T) + B, where a is the amplitude in ?m (micrometers), T is the period in seconds, and B accounts for the weakening of the seismic wave due to the distance from the epicenter. Compute the earthquake magnitude R when a = 320, T = 5, and B = 3.5. (Round to the nearest ten-thousandth.)
