On the Richter scale, the magnitude, R, of an earthquake of intensity I is given by R

Question:

On the Richter scale, the magnitude, R, of an earthquake of intensity I is given by R = log I /I0 , where I₀ is the intensity of a barely felt zero-level earthquake. If the intensity of an earthquake is 1000I₀, what is its magnitude on the Richter scale?
