PLEASE HELP-DUE APRIL 5TH, 2011!!!!
EARTHQUAKES an earthquake rated at 3.5 on the Richter scale is felt by many people, and an earthquake rated at 4.5 may cause local damage. The Richter scale magnitude reading m is given by m = log (base 10) x, where x represents the amplitude of the seismic wave causing ground motion. How many times greater is the amplitude of an earthquake that measures 4.5 on the Richter scale than one that measures 3.5?

log(4.5) / log(3.5) = 1.200.
