What's the best way to work out log's without a calculator / other aids?
The question is what is the answer.
I know the answer is and I can work it out simply on a calculator. How do I do it without though?
I'm not sure the working method (without trial and error), any help would be appreciated. Sorry if it's pretty basic.
I'll put another one in here instead of starting up a new thread.
I need to simplify this logarithm. (By solving)
So far I change that (I don't know if it breaks rules or not) to ...
That gives me a nasty decimal answer which I know isn't right. Correct answer is listed as one but I'm not sure how to manipulate it to cancel it out.
Thank you again for your help so far.
don't worry about "clogging" the forum. the mods are here to make sure that does not happen. in fact, putting new questions in new threads keep the forum organized and so helps with keeping the forum clog free. in addition, you are more likely to get your question answered quickly if you post in a new thread. (users may ignore the thread if they see that someone has responded to it, especially if that someone is a Helper. so if that helper is not around, you won't get your questions answered as quickly as possible)I'll try and put new questions in new threads now, didn't want to clog the forums with my basic questions though
take care. good luck with your studies
