Solve the following equation. By now you should know that when the base of the exponent and the base of the logarithm are the same the left side can be written x. Solving Logarithmic Equations Explanation Examples As you well know that a logarithm is a mathematical operation that is the inverse of exponentiation.

Learn how to condense logarithmic expressions. Were asked to solve the log of X plus log of 3 is equal to 2 log of 4 minus log of 2 so let me just rewrite it so we have the log of X plus the log of 3 is equal to 2 times the log of 4 minus the log of 2 or the logarithm of 2 and just as a reminder whenever you see a logarithm written without a base the implicit base is 10 so we could write 10 here 10 here 10 here and 10 here but for the. Log 4 x 4 log 4 8 2.

Log5x75 is x 5. Steps for Solving Logarithmic Equations Containing Only Logarithms Step 1. Log 4 x 4 log 4 8 2.
