WebJun 9, 2014 · By definition, the logarithm of a number N in any particular base B is equal to log (N)/log (B), where log () can be either the natural logarithm (base e ), or any other base (e.g. base 10), as long as both log (N) and log (B) are calculated with respect to the same base. Share. Improve this answer. Follow. answered Jun 9, 2014 at 15:09. twalberg. WebI'm not sure how you made that last step. log2 (b) / 2 = log2 (b) / log2 (4) = log4 (b) . To get log2 (b^2) you'll have to arbitrarily multiply log2 (b) / 2 by 4, which is not a legal operation. Regardless, you can use any base you want, unless some particular base allows to simplify the expression further. atas talian vs dalam talian
