Yes I know where the Log button is.. hmm.
Weird, I don't seem to get the correct result actually... should it be log(e^38.8)? because e is demanding something to the power of... and I suppose you mean that e should be within the brackets. There's no log(to the base of e) button.. if that is what I should have...
I have just told you how to find the log base e button. Irregardless of this, you don't need it .... Just use the log button (which is actually the log base 10 button).
I don't know why you would be wanting to use the 'e to the power of' button .... What I have posted does not involve exponentials.
You need to read again the replies you've been given and then press the correct buttons on your calculator.
Found this on the net about bases by the way, if someone else needs it: ln(2) is just the log of 2, and ln(2)/ln(10) is log of 2, base 10. You can also see that ln(2)/ln(e), the base e log which is the natural log, will be just ln(2) since ln(e) evaluates to 1.
The thing is, I have to use the e button and.. well, it is apparently only e to the power of something on my calculator, should I just disregard e? What should b be? I get 3.70
I am a bit confused and it could be due to my rather poor English...
