How many times more intense is an earthquake that measures 6.8 on the Richter scale than one that measures 4.2? Recall that the Richter scale defines magnitude of an earthquake with the equation:
M=log(I/S) , where I is the intensity of the earthquake being measured, and S is the intensity of a standard earthquake.

do you want the equation?

anonymous · Answer

Yes, this is the hint my teacher gave me. (Hint: Create a system of equations, then, using the elimination method, cancel S.  You will have to use a logarithmic property to do that.)

WRITE alll the things you understand in form of equation

anonymous · Answer

Is it going to be M=log(6.8/4.2) ?

anonymous · Answer

yes
