I am seeking some quick advice for these two problems I have on this physics homework I am completing right now. Please look below. There are 2 questions.

1. The population of a country doubles every 24 years. How long will it take for the populartion to increase by a factor of 5?

2. The 1970 earthquake in Peru registered 7.7 on the Richter scale. How much more intense was this earthquake compared to the tremor in Ontario in 2002 that was measuered to be 5.2 on the Richter scale?

I have a test coming up and I need to know how to solve these questions. Regarding #2 it is going to use log's. For example a earthquake at a scale of 4 is 10 times more intense than one at a scale of 3. (On the Richter scale).

Any help would be GREATLY appreciated. Thank you very, very much in advance.

Cya,
