Math question, loosely related to python... The python "Think Like a Computer Scientist" pdf tutorial assumes you have a familiarity with logarithmic equations and whatever sin stands for (will look into that next). I never learned this stuff. I understand some of the basic mechanics here, like that a log is sort of a reverse exponent. I can do a simple equation like finding the log of 36 with a base of 6. But I don't get why the logarithm of 1 is always equal to 0

Best ResponseYou've already chosen the best response.0Heres an example problem Evaluate log1 with a base of 8. 8 to what exponent produces 1? 0 with a base of 8 = 1. log1 with a base of 8 = 0. We can observe that, in any base, the logarithm of 1 is 0. so: log1 with base of b = 0

Best ResponseYou've already chosen the best response.0why is the log of 1 with a base of 8 equal to 0 rather than 1/8 ?? How does that make sense?

Best ResponseYou've already chosen the best response.0(8 *1) /8 = 1/8 or 0.125 so 0.125 * 8 = 1 Didn't I just equate the logarithm of 1 with a base of 8??

Best ResponseYou've already chosen the best response.0Hi Evil  this is something I had real problems remembering, so I had to check for myself before the light came on again! I think of logs exactly as the reverse of exponents  it's the only way it makes sense to me, and by doing an exponent first, you can make your own language for the logs e.g. exp 8 (3) is just "8 raised to the power of 3"  log 8 (3) to me can be rephrased as "8 to the power of what number will give you 3?" When I think of it like that, then exp (0) in any base is a number to the power of zero, and that always gives you the answer of one. Doing this in reverse (i.e. log(1) ) should always result in zero. "(base) to the power of what number will give you 1?" I really hope this isn't even more confusing!!

Best ResponseYou've already chosen the best response.0Any number to the power of 0 is 1. That's what was throwing me off. It would seem that it doesn't make sense, that rather a number to the power of nothing would naturally be nothing, but that apparently isn't the case. Next I've got to find out why (but that's a problem for a math forum  as was this one, really)... Thank you both for your help!
