sorry this should go under the " Homework, Coursework, & Textbook Questions" forum. please delete. i will repost. Okay i did a search for logarithmic properties and logarithms and couldn't seem to find an explanation for how this particular property works. (log base c of a ) ^ b = b (log base c of a) when i input simple numbers like : PHP: a=4 b=3 c=2 Log base 2 of 4 obvioussly the answer is 2, but 2^3 /= (does not equel) 3 x 2. i dont' know how to make sense of this discrepency. i imagine i'm just reading it wrong.
