1. On October 20,2004, a 5.0 earthquake on the Richter scale hit Los Angeles. Three
days later, a 2.0 earthquake hit Los Angeles. How many times stronger was the
5.0 earthquake from the 2.0 earthquake? Calculate the answer as a power of 10
and show your work.
2. Practice: A 6.0 earthquake just hit Los Angeles, while a 2.0
hit San Palm Springs later in the day. How many times
stronger was the 6.0 earthquake from the 2.0 earthquake?
Calculate the answer as a power of 10 and show your work.
