In this case we can use the reverse of the above identity.

Adding logs with same base math. Examples of how to combine or condense logarithms. Log base 2 8x 2y 2 z log base 2 8 log base 2 x 2 log base 2 y 2 log base 2 z next if you have a log of something with a power you can bring the power out front and multiply it by the log. Exponent of log rule raising the logarithm of a number to its base equals the number. Now we have two powers of the same base.

The logarithm of a fraction is equal to the logarithm of the numerator minus the logarithm of the denominator. If you have the log of a quotient it is the same as the difference of the logs of the terms separately. Combine that with the preceding equation to obtain. B log b xy xy.

B log b xy b log b x log b y. The logarithm of an exponential number where its base is the same as the base of the log equals the exponent. Now apply the compact definition to the left hand side. But when you multiply two powers of the same base you add their exponents.

So the right hand side becomes. 1 multiplication inside the log can be turned into addition outside the log and vice versa. The multiplication rule of logarithms applies when we are adding two logarithms together that have the same base. 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.
