Solving logarithmic equations for x

WebNov 25, 2024 · Then take logs of both sides. log (2^n) = log (X+1). Then you can use properties of logs to get n*log2 = log(X+1) and solve for n = log(x+1)/log2. That's not quite what you want because you need the formula to return whole numbers for n, but you can fix that by saying n = ceil(log(X+1)/log2) where ceil is the rounding up function.
