Separate Equation Log For Free

We have already seen that every logarithmic equation logb(x)=y is equivalent to the exponential equation by=x. We can use this fact, along with the rules of logarithms, to solve logarithmic equations where the argument is an algebraic expression. For example, consider the equation log2(2)+log2(3x?5)=3.

Use the power property of logarithms to simplify the logarithm on the left side of the equation. Remember that log 4 is a number. You can divide both sides of the equation by log 4 to get x by itself. Use a calculator to evaluate the logarithms and the quotient.

This time i only have a b for my base.

Division. The rule when you divide two values with the same base is to subtract the exponents. Therefore, the rule for division is to subtract the logarithms. The log of a quotient is the difference of the logs.

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).
