Nov 16, 2022 · We give the basic properties and graphs of logarithm functions. In addition, we discuss how to evaluate some basic logarithms including the use of the change of base formula.

Jan 8, 2026 · In mathematics, a logarithm is the inverse operation of exponentiation. It is defined as the power to which the base number must be raised to get the given number. Logarithms serve as …

Learn about the properties of logarithms that help us rewrite logarithmic expressions, and about the change of base rule that allows us to evaluate any logarithm we want using the calculator.

Jul 8, 2025 · To represent y as a function of x, we use a logarithmic function of the form y = log b (x). The base b logarithm of a number is the exponent by which we must raise b to get that number.

As mentioned earlier for exponential functions, the number \ (e\approx 2.71828\ldots\) is the most convenient base to use in Calculus. For this reason we give the logarithm with base \ (e\) a special …
