In mathematics, logarithmic refers to the logarithm, which is a mathematical function that measures the exponent needed to produce a given number.

The logarithmic function is denoted as log base b of x, usually written as logₓ(b), where x is the base and b is the argument or input.

The logarithm can be defined using exponential notation. For example, if we have x = b^y, then the logarithm becomes y = logₓ(b). This means that the logarithm tells us “to what power” we need to raise the base (x) to get the argument (b).

Logarithms have several useful properties that make them applicable in various fields of science, engineering, and finance. Some of these properties include:

1. The logarithm of a product: logₓ(ab) = logₓ(a) + logₓ(b). This property allows us to break down a multiplication problem into an addition problem using logarithms.

2. The logarithm of a quotient: logₓ(a/b) = logₓ(a) – logₓ(b). Similar to the previous property, this allows us to simplify division problems using logarithms.

3. The logarithm of a power: logₓ(a^y) = y * logₓ(a). This property enables us to simplify exponentiation problems using logarithms.

4. Change of base formula: logₓ(b) = logᵤ(b) / logᵤ(x). This formula allows us to convert a logarithm from one base (u) to another base (x).

Logarithms are used in various areas such as solving exponential equations, analyzing exponential growth and decay, calculating interest rates in finance, measuring the loudness of sounds in decibels, and many more.

I hope this explanation helps in understanding the concept of logarithmic functions. Let me know if you have any further questions!
