![]() 3) An exponent on everything inside a log can be moved out front as a multiplier, and vice versa. ![]() 2) Division inside the log can be turned into subtraction outside the log, and vice versa.

Then you must include on every digital page view the following attribution: If you are redistributing all or part of this book in a digital format, For our purposes, expanding a logarithm means writing it as the sum of two logarithms or more. Then you must include on every physical page the following attribution: Example: Expanding logarithms using the product rule. To solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. If you are redistributing all or part of this book in a print format, How do you expand and condense logarithms - To expand logarithms, write them as a sum or difference of logarithms where the power rule is applied if. Notice that the two factors of the argument of the logarithm are blueD 5 5 and greenD y y. We expand and condense logarithms using the laws of logarithms and the laws of exponents. ![]() Then use the multiplication property from the prior video to convert. Then multiply through by log (3) to get log (x) 2log (3). Then replace both side with 10 raised to the power of each side, to get log (x)/log (3) 2. To Condense Logarithms is to write several logarithmic expressions as a single logarithmic expression. Well, first you can use the property from this video to convert the left side, to get log ( log (x) / log (3) ) log (2). There is no way to expand the logarithm of a sum or difference inside the argument of the logarithm. expandtrig To expand trigonometric functions. For our purposes, expanding a logarithm means writing it as the sum of two logarithms or more. To Expand Logarithms is to write a single logarithmic expression as several logarithmic expressions. How to expand or condense a logarithmic equation - No. Want to cite, share, or modify this book? This book uses the trigonometry logarithm Limits for Trigonometric, exponential and logarithmic. = 6 l o g 6 2 + 3 l o g 6 x + l o g 6 ( 4 x + 1 ) − l o g 6 ( 2 x − 1 ) Apply the Power Rule. = l o g 6 2 6 + l o g 6 x 3 + l o g 6 ( 4 x + 1 ) − l o g 6 ( 2 x − 1 ) Simplify by writing 64 as 2 6. L o g 6 ( 64 x 3 ( 4 x + 1 ) ( 2 x − 1 ) ) = l o g 6 64 + l o g 6 x 3 + l o g 6 ( 4 x + 1 ) − l o g 6 ( 2 x − 1 ) Apply the Quotient Rule.
