Definitions:

Logarithm

The logarithm is the power to which a number, called the base, must be raised to produce a given number. For example, in base 10, the logarithm of 1000 is 3 because 10 raised to the power of 3 is 1000.

Logarithm

The power to which a base, typically 10 or e, must be raised to produce a given number.

Logarithm

The exponent or power to which a base number must be raised to produce a given number.

Logarithmic Equation
