# Log and Antilog Formula

Here is the log and antilog formula which is used to calculate the logarithm and antilogarithm values. Logarithm & Anti-logarithms deal with 3 kinds of numbers ie., "Base to", "Value" and "answer". The logarithm to base 10 is called the common logarithm in mathematics. Anti-log is the inverse of the log function, it is also known as 10x. The base values of log functions may either be 10, 2 or e. Both log and antilog has many applications in science and engineering.

#### Formula:

Computation of log (logbx):
logbx = y implies by = x.

Where,

b = base
y = number
x = log value

Computation of Antilog:
y = 10x

Where,

x = number
y = antilog value
