Is it possible for a logarithm to equal a negative number?
Yes. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log(0.1) = -1, log(0.01) = -2, log(0.001) = -3, etc.
Is log 10 100 equals 2 is common logarithm?
Yes. Logarithms to the base 10 are called common logarithms, and 2 is the correct common logarithm for 100.
What is log 10 100?
The logarithm to the base 10 of 100 is 2, because 102 = 100.
What is the logarithm of 100?
logarithm of 100 = 2. If there is not a subscript number on your log, you assume it to be 10. In other words, the little subscript would be the base if you were raising it to a power, and the big number is the answer of the power. For example, log (base 10) 100 = 2 because 10 (the base) raised to a power of 2 (the log answer) = 100 (the number you just took the log of.)
What is a natural logarithm used for?
The natural logarithm (ln) is used when you have log base e
