4 Αυγ 2024 · No the argument of logarithm can’t be negative, however, log of any number can give a negative value. What are Logarithms used for? Logarithm is used to find the power a number must be raised to yield a particular result.
Logarithms can also be negative: = since = =. log 10 150 is approximately 2.176, which lies between 2 and 3, just as 150 lies between 10 2 = 100 and 10 3 = 1000. For any base b, log b b = 1 and log b 1 = 0, since b 1 = b and b 0 = 1, respectively.
The negative logarithms. We know that logarithms are not defined for negative values.
Discover the link between exponential function bⁿ = M and logₐM = N in this article about Logarithms Explained. Understanding this basic idea helps us solve algebra problems that require switching between logarithmic and exponential forms.
Negative Log Property. The negative logs are of the form −log b a. We can calculate this using the power rule of logarithms. −log b a = log b a-1 = log b (1/a) Thus, −log b a = log b (1/a) i.e., To convert a negative log into a positive log, we can just take the reciprocal of the argument.
Looking at that table, see how positive, zero or negative logarithms are really part of the same (fairly simple) pattern. The Word "Logarithm" is a word made up by Scottish mathematician John Napier (1550-1617), from the Greek word logos meaning "proportion, ratio or word" and arithmos meaning "number", ... which together makes "ratio-number" !
