1) ln( )=2.

We know: ln( )=n ln(x)

-> 2ln(x)=ln(2) --> ln(x)= . --> x= .

Is that correct? Because my booklet, again, says something different ;)

2) are generally all logarithmic rules appliable for ln?

Yes sure, sry i meant ln(

__x^2__)=2, not x^1/2. But thats no big change, because in my booklet the solution is +/-e and this is nonsense, isn't it? - Apr 8th 2010, 07:37 AMdwsmith

You can't have a negative value in the natural function since the domain is (0,infinity)

-e=-2.78......
