The magnitude R (on the Richter scale) of an earthquake of Intensity / is defined as log (1) R = log| where Io = minimum intensity used for comparison. Ms. Cohen felt an earthquake in Los Angeles that had an intensity of (5 x 10) (Io). What was its magnitude, to one decimal place, on the Richter scale? Be sure to show and explain your work, including breaking down the logarithm into its separate parts. Part 2 - Find the error(s) and solve the problem correctly. Solve. Be sure to show and explain your work. log4(x + 3) + log4(x 3) = 2 Answer: log4(x + 3) + log(x 3) = 2 log4(x+3+x 3) = 2 log4 (2x) = 2 4 = 2x 16 = 2x 8=2 Part 3 - Discussion Question How do we know that e* and Ina are inverses of each other?
