Condense log experessions12/8/2023 We will learn later how to change the base of any logarithm before condensing. It is important to remember that the logarithms must have the same base to be combined. Here is the rule, just in case you forgot. ![]() Since we want to transform the left side into a single logarithmic equation, we should use the Product Rule in reverse to condense it. Here is a video with a similar example worked out. Condense logarithmic expressions We can use the rules of logarithms we just learned to condense sums, differences, and products with the same base as a single logarithm. Example 1: Solve the logarithmic equation. Since these base of the exponential expressions are the same, combine using the power and quotient rules for exponent.įind a common denominator to combine the fractions. Product Rule for Logarithms: Quotient Rule for Logarithms: The expressions inside the logarithm will be positioned in the numerator if the logarithm is positive or will be positioned in the denominator if the logarithm is negative. A fourth root is the same as the one-fourth powerĬondense the logarithms using the product and quotient rule. A square root is the same as the one-half power. The coefficient of 1/6 on the middle term becomes the power on the expression inside the logarithmĪ radical can be written as a fractional power. Use the Properties of Logarithms to condense the logarithm. ![]() Whenever possible, evaluate logarithmic expressions. To condense logarithmic expressions with the same base into one logarithm, we start by using the Power Property to get the coefficients of the log terms to be one and then the Product and Quotient Properties as needed.
