The logarithm of a number with base=B is written as [ logB(N) ].

If the base is 10, it's called the "common logarithm" of N and the base isn't written. [ log(N) ].

If the base is 'e', it's called the "natural logarithm" of N, and written [ ln(N) ].

In the continuous compounding equation e is the natural log to the base 10?

A "natural logarithm" is a logarithm to the base e, notto the base 10. Base 10 is sometimes called "common logarithm". The number e is approximately 2.71828.


Compare and contrast common logarithm with natural logarithm?

The natural logarithm is the logarithm having base e, whereThe common logarithm is the logarithm to base 10.You can probably find both definitions in wikipedia.


How do you write 0.0001 in exponential notation using a base of 10?

0.0001 in exponential notation using a base of 10 is: 1.0 × 10-4


How do you write natural logarithms?

A natural logarithm or a logarithm to the base e are written as: ln(X) as opposed to loge(X)


Is ln equal to log?

Most people do not mean the same thing when they write "ln" and "log". Both refer to a logarithm, but the base for "ln" is the number e (a special number roughly equal to 2.1781) while the base for "log" is 10, unless otherwise specified. "ln" is called the natural logarithm and "log" is called the common logarithm when it refers to the base 10 logarithm.A quick example of how they are different:log 10,000 = 4ln 10,000 = 9.21The reason for this is that the logarithm is the inverse of (that is, it undoes) exponentiation. The first example asks "what power do I have to raise 10 to in order to get 10,000?" The exponentiation related to the first example is 104 = 10,000. The second example asks "what power do I have to raise e to in order to get 10,000?" The exponentiation related to it is e9.21 = 10,000.
