In a mobile phone network, how many times as strong would a signal be expected to be at 200 m from a base station, compared with at 600 m?

1. Your teacher probably wants 3^2 or 9 times.
   
   It depends on the unit of measure you are using for "as strong"...power intensity, Electric field intensity, Magnetic Field intensity.
   
   And, there are logrithmic measures for all of these two.
   But if you consider just energy spreading, the Power density= Power/area
   and area is proportional to radius^2
   
   so the power intensity change is 1/(1/3)^2=9

2. Well, let me put it this way. If the signal strength at 600 m is represented by a baby sneeze, then the signal strength at 200 m would be as loud as a clown blowing a horn right next to your ear. So, I'd say the signal strength would be 81 times stronger at 200 m compared to 600 m. So, go ahead and enjoy that circus-level signal strength!
