A logarithm is the mathematical inverse of an exponent. It represents the power to which a base number must be raised to equal a given number. For example, the logarithm base 10 of 100 is 2, because 10 to the power of 2 equals 100.
The main properties of logarithms include the product property, quotient property, power property, and change of base property. These properties allow us to simplify and solve logarithmic equations.
The product property states that the logarithm of a product is equal to the sum of the logarithms of the individual factors. In other words, logb(xy) = logb(x) + logb(y). This property is useful for expanding logarithms and solving equations with multiple terms.
The power property states that the logarithm of a number raised to a power is equal to that power multiplied by the logarithm of the original number. In other words, logb(xn) = n * logb(x). This property is useful for simplifying logarithmic expressions and solving exponential equations.
The change of base property states that the logarithm of a number in one base can be rewritten as the logarithm of the same number in a different base divided by the logarithm of the original base. In other words, logb(x) = loga(x) / loga(b). This property allows us to solve logarithmic equations by changing the base to a more convenient one, such as base 10 or base e.
