Simplifying logarithms with different bases
Webb7. Dividing logs which have the same base changes the base of the log. That is log a log b = log b a. It doesn't matter what base we were using on the left hand side. It will change the base of the log as above. log 125 log 25 = log 25 125 and 25 3 2 = 125. Share. WebbWhen adding two logarithms, in the same base b, the following simplification can always be made: logb(a) + logb(c) = logb(a × c) Example The expression: log3(5) + log3(8) can …

Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions". Doing one, then the other, gets us back to where we started: Doing ax then loga gives us back x: loga(ax) = x. Doing loga then ax gives us back x: aloga(x) = x.
WebbWhen you have logarithms with different bases, it means that you have a logarithmic equation or expression where the bases are of different numbers. The way to go about this is to use a formula called the change of base formula. The aim here is to make the different bases equal. That way, you will be able to get a solution easily.

In my example I am trying to solve the following: $$ n^{\log_\frac{3}{2}(1)} \tag{1} $$ This … WebbRemember that a logarithm is the power to which a number must be raised to obtain another number. For example, the base 10 logarithm of 100 is 2, since 10 raised to the power of 2 equals 100: \log (100)=2 log(100) = 2. because: { {10}^2}=100 102 = 100. The base is the number that is being raised to a power. We can use logarithms with any base.
