WebApr 23, 2024 · The first link is simply using the basic rules for logarithms - the log of a product is equal to the sum of the logs (working in base 10). As an example, take log(3025) = log(3.025 × 103) = log(3.025) + log(103) = log(3.025) + 3 ≈ 3.48 (using that log(3) is 0.48). The power of 10 was chosen because log(3) was known. – Mark Bennet optecure bone graftWebA logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2 because 102 = 100 This is an example of a base-ten logarithm. opted for 115bacWebApr 12, 2024 · It finds the FIRST index of the number at that point in the array, and check if it's the same index as minNum, and if it is it excludes it. So the first 1 it sees has a first index of 2, so it filters it out, and the second 1 it sees also has a first index of 2 (because the first index of the value 1 is still 2), so it filters that out too.
