Here is a video with a similar example worked out. Condense each expression to a single logarithm. Detailed step by step solutions to your Condensing Logarithms problems with our math solver. Expand these: a) log 45x 3y b) ln c) log 3x-5 7 b 3 1+a 2 5. Condensing Logarithms Calculator online with solution and steps. 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. In solving equations, it will be helpful to expand and condense logarithmic expressions. 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. Expanding and Condensing Logarithms Condense each expression to a single logarithm.
#CONDENSE LOG EXPERESSIONS HOW TO#
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. A square root is the same as the one-half power. We can use the rules of logarithms we just learned to condense sums, differences, and products with the same base as a single logarithm. 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. Whenever possible, evaluate logarithmic expressions.
