Introduction to Logarithms. In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2 s to get 8. So the logarithm is 3. How to Write it. We write it like this: log2(8) = 3.
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.
9 Ιαν 2017 · So, if we want to define the complex logarithm, we do so as follows: log(z) = log(| z | eiθ) = log(| z |) + log(eiθ) = log(| z |) + iθ. In particular, the logarithm of a negative real number x can then be calculated as log(x) = log(| x | eiπ) = log(| x |) + log(eiπ) = log(| x |) + iπ.
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.
Logarithm of negative number The base b real logarithm of x when x<=0 is undefined when x is negative or equal to zero: log b ( x ) is undefined when x ≤ 0
4 Αυγ 2024 · Logarithm is a mathematical function that represents the exponent to which a fixed number, known as the base, must be raised to produce a given number. In other words, it is the inverse operation of exponentiation.
