Question 206756: This has me confused.....
Using Richter scale equation M = log I/I^(0) where M is the magnitude of an earthquake, I is the intensity of the shock waves, and I^(0) is the measure of the intensity of a zero-level earthquake.
On May 21, 2003, an earthquake struck Northern Algeria. The quake had an intensity of I = 6,309,573I^(0). Find the Richter scale magnitude of the earthquake. Round to the nearest tenth.
I cant figure this out, can someone explain?
Thank you!

You can put this solution on YOUR website! Using Richter scale equation M = log[I/I(o)] where M is the magnitude of an earthquake, I is the intensity of the shock waves, and I(o) is the measure of the intensity of a zero-level earthquake.
On May 21, 2003, an earthquake struck Northern Algeria. The quake had an intensity of I = 6,309,573I(o). Find the Richter scale magnitude of the earthquake. Round to the nearest tenth.
----------------
M = log[6,309,573*I(o)]/I(o)
M = log[6,309,573]
M = 6.79999..
