Weblneiπ = ln( − 1) Simplified: iπ = ln( − 1) So, now that we know what ln( − 1) is, we can substitute back into our equation: logb( −x) = lnx + iπ lnb. Now you have a formula for finding logs of negative numbers. So, if we want to evaluate something like log210, we can simply plug in a few values: log2( −10) = ln10+ iπ ln2. WebMultiplying by 1/81 is easier to work out than 1/9 divided by 81. Always remember: dividing by a number is the same as multiplying it by it's inverse. Example: 10/2 is the same a 10*1/2=5. 20/4 is the same as 20*1/4=5. If you want to multiply instead of divide, just take the inverse or reciprocal of the number you want to divide by. birthday ideas for girls giftsWebJan 8, 2015 · Can the argument of a logarithm and its base be negative at the same time? 0.
