An earthquake registered 7.4 on the Richter scale. If the reference intensity of this quake was 2.0 × 1011, what was its intensity?

ChampionG:

The formula to find the intensity is R = logI R equals the magnitude, which is 7.4 7.4 = logI Change that to exponential form: 10^7.4 = I The intensity is 25,118,864.32
