The logarithm of a number with a given base is the exponent to which it is necessary to raise the base in order to obtain the number.
a is the base, x is the number and y is the logarithm.
Calculate the Logarithm:
The common logarithm has a base of 10. It is represented by log (x).
|y = log x||−3||−2||−1||0||1||2||3|
The natural logarithm has a base of e (an irrational number with an approximate value of 2.718281828). It is represented by ln (x).
