How to Solve Equations Involving Logarithms
First, apply the 4 basic rules of logs to simplify the equation. The 4 rules hold true regardless of the base of the logarithm. (1) log(a) + log(b) = log(ab) (2) log(a) - log(b) = log(a/b) (3) log(a^n) = n[log(a)] (4) log(1) = 0 For example... Read More »

http://www.flickr.com/photos/dwread/6401… I'm not sure this is correct, because when I test it for x = ⅓, it comes out log(⅓² + 1) - 2log(⅓) = 1.08 Could be rounding error, though. Thank you for your service to our country.

Ale made a typo... log_4 (2) should be 1/2 and not 2. 2^a = 3 alog2 = log3 a = log(3)/log(2) Using x... 4^x = 18 2^(2x) = 18 2xlog2 = log18 2xlog2 = log(6) + log(3) x = (log(6) + log(3))/ 2log2 x = log(6)/2log(2) + (a/2) x = (a+1)/2 + (a/2)...
