Let's say that this thing right over here evaluates to y so log base b of a is equal to y.

The sum of the logs is the log of the product. The log of a sum cannot be simplified. The log of a difference is NOT the difference of the logs. The difference of the logs is the log of the quotient.

Properties of Logarithms Adding Logs - Visualizing Algebra - YouTube YouTube Start of suggested clip End of suggested clip The first property states that if we add two logarithms together that have the same base then we canMoreThe first property states that if we add two logarithms together that have the same base then we can just multiply. The numbers together for example if we have log base 2 of 4 plus log base 2 of 8.

Logs of the same base can be added together by multiplying their arguments: log(xy) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) - log(y).
