Question 1005846: Can y'all show me step by step on how to do this word problem? it says An earthquake was recorded with an intensity which was 501,187 times more powerful than a reference level earthquake, or 501,187 x I0. What is the magnitude of this earthquake on the richter scale (round to the nearest tenth)? The magnitude on the Richter scale of an earthquake of intensity I is log10(I/I0).

You can put this solution on YOUR website!
I=%22501%2C187%22I%5B0%5D , so the magnitude is
.

NOTES:
If the base of a logarithm is 10 , we usually do not write it,
so log%2810%2C%22501%2C187%22%29=log%28%22501%2C187%22%29 .
You can calculate log%28%22501%2C187%22%29 with most calculators.
