WebJan 25, 2016 · If you are only working in real numbers, no, you cannot take the natural log of a negative number. If you are working in complex (imaginary) numbers, however, it is possible. Explanation below. Notice that e^(i pi) = -1 so in some sense you might like to define: ln(-1) = pi i. WebWhen I take the log of both sides of an equation, I can use any log I like (base-10 log, base-2 log, natural log, etc), but some are sometimes more useful than others. Since the base in the equation " 2 x = 30 " is " 2 ", I might try using a base- 2 log:
