And that's it we've written it as a sum of two logs of the same base.

How to find the inverse of a logarithmic function, f(x) = log2 (x) YouTube Start of suggested clip End of suggested clip All right remember to find the inverse the main thing we need to do is change our function in forMoreAll right remember to find the inverse the main thing we need to do is change our function in for a y so now we have a an equation. Then we swap the x and the y's. Right and now we solve for y.

To write the sum or difference of logarithms as a single logarithm, you will need to learn a few rules. The rules are ln AB = ln A + ln B. This is the addition rule. The multiplication rule of logarithm states that ln A/b = ln A - ln B.
