............since

Now we can just drop the logs:

I think you can take it from here

b) log3 (x+3) - log3 (x-3) = 1

...........since if , then

...and i think you can solve that equation

right off the bat!c) logn 1 = x

The always, i don't care what the base is, the log of 1 is 0, why?

Anything raised to the zero gives one, so the power is zero
