31 Ιουλ 2024 · The logarithm in base 2 of 256 is 8. To find this result, consider the following formula: 2 x = 256. The logarithm corresponds to the following equation: log2(256) = x. In this case, we can check the powers of 2 to see if we can find the value of x: 2 0 = 1, 2 1 = 2, 2 2 = 4, …, 2 7 = 128, and 2 8 = 256.
Certain logarithms can be easy to compute in your mind, e.g. log 10 (1000) = 3 since 10^3 = 1000. A general solution is to calculate logs using power series or the arithmetic-geometric mean. A pre-calculated table can also be of use if only a range of bases and logarithms are of interest on a daily basis.
