   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.

   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. See: log of negative number. Logarithm of 0. The base b logarithm of zero is undefined: log b (0) is undefined. The limit of the base b logarithm of x, when x approaches zero, is minus ...

   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.

   28 Μαΐ 2024 · However, negative logarithms are formed when the argument is between 0 and 1. In log b x < 0, for 0 < x < 1, ‘b’ is the base, and ‘x’ is the argument. For example, log(0.0001) = -4 gives a negative value, and its exponential form, 10 -4 = 0.0001, gives a decimal.

   While the value of a logarithm can be a negative number, the argument (x-value) of any logarithm cannot be negative. This is because the base of a logarithm can only be a positive number greater than 1, and a positive number raised to anything will be a positive number: base > 1.
