Please Help The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the intensity of a reference earthquake, I0.

M=(I/Io)

Which equation could be used to find the intensity of an earthquake with a Richter scale magnitude of 4.8 in reference to an earthquake with an intensity of 1?

4.8=log(I)
I=log(1/4.8)
I=log(4.8)
4.8=log(1/I)
