The sky is blue. That's basicall what you're telling us. :P

2. manhtruongz Group Title

maybe

3. funinabox Group Title

if this is supposed to be true/false, it would be false, as logarithms can only be positive > 0

4. across Group Title

Are you looking for the domain of that expression?

6. across Group Title

I think everyone in OS is trained to think in $$\mathbb{R}$$. :P

7. funinabox Group Title

well i'm just retriceumminngg that this would be in real numbers lol

8. manhtruongz Group Title

9. funinabox Group Title

i typed "assuming" and it came out retriceumminngg lol what the..

But anyway, Notice that$\ln x<0\text{ for all }x\in(0,1).$

12. asnaseer Group Title

does the "In" in your question represent log or is your question more like: In the expression x < 0, what is the solution in interval notation?

13. 4086665195 Group Title

yea

14. across Group Title

@asnaseer, that's genius. lol!

15. asnaseer Group Title

lol - which one?

16. asnaseer Group Title

@across - just looking at it from a different point of view that's all - no geniuses were involved in the formulation of this thought. :)

17. across Group Title

To me, shifting one's point of view is more genius than applying Schroedinger's equation to solve problems. :P

18. asnaseer Group Title

hehe - I've missed you and your sense of humour! :D

19. asnaseer Group Title

@4086665195 - so which one is it: a) "In" represents log, or, b) "In" represents the work "in"

*word

and e^x> 3,the answer is x>ln3,which means (ln3,+infinity)?
