> 149,135,151 This is 8-point-something as you say. 1.49 is in between 1.2 and 1.6 and I have memorised log(1.2)=0.1 and log(1.6)=0.2, so I would think log(1.5) is close to 0.17, using sloppy linear interpolation. That would make log(149,135,151) approximately 8.17. My calculator also says 8.17. Your guess was good! I have found linear interpolation such an intuitive approximation method that the tradeoff of having to memorise more logarithms is worth it. |
