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.

There are values for which the logarithm function returns negative results, e.g. log 2 0.125 = -3, since 2-3 = 1 / 2 3 = 1/8 = 0.125. Example log calculations log 2 64 = 6 , since 2 6 = 2 x 2 x 2 x 2 x 2 x 2 = 64.
Rewrite log2 (8) = x log 2 (8) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b (x) = y is equivalent to by = x b y = x. Create equivalent expressions in the equation that all have equal bases.
