What is the base for the common logarithm?
Common logarithm identity. as procedures exist for determining the numerical value for logarithm base "e" and logarithm base 2. Common logarithm In mathematics, the common logarithm is the logarithm with base 10. It is also known as the decadic logarithm and as the decimal logarithm, named after its base, or Briggsian logarithm, after Henry Briggs, an English mathematician who pioneered its use, as well as "standard logarithm". Historically, it was known as "logarithmus decimalis" or "logarithmus decadis". It is indicated by log("x"), or sometimes Log("x") with a capital "L" (however, this notation is ambiguous since it can also mean the complex natural
Logarithm real power, always producing a positive result, so the logarithm for any two positive real numbers and where is not equal to , is always a unique real number . More explicitly, the defining relation between exponentiation and logarithm is: For example, , as . The logarithm to base (that is ) is called the common logarithm and has many applications in science and engineering. The natural logarithm has the number (that is ) as its base; its use is widespread in mathematics and physics, because of its simpler derivative. The binary logarithm uses base (that is ) and is
