: Colombian Earthquake of 1906 At 8.6 on the richter scale, the Colombian earthquake of January 31, 1906, was one of the strongest earthquakes on record. Use the formula log(I)-log(Io) to write I as a multiple of Io for this earthquake. This question is from textbook College Algebra

log(I)-log(Io) =
log (I/Io) = 8.6
I/Io = 10^8.6
I/Io = 398107170.6
Since we are given only two significant figures, our best answer is
I = 400000000*Io
