What Does A Negative Log Mean? A negative log means that we will use a negative exponent (power) when we convert from log form to exponential form. Remember that a negative exponent means that we are dividing by a number rather than multiplying.
5 Ιουν 2024 · Using this calculator, you can find the negative logarithm of any number with any chosen base. For details on logarithms and how to find the negative log of a number, read the description given below.
11 Οκτ 2016 · Negative numbers, and the number 0, aren’t acceptable arguments to plug into a logarithm, but why? The reason has more to do with the base of the logarithm than with the argument of the logarithm. To understand why, we have to understand that logarithms are actually like exponents: the base of a logarithm is also the base of a power function.
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.
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
