Oh...no way would I get that - I only know how to turn my computer on and off! Just gave it a shot for you!
I didn't even understand the question! 
When using decimal notation is STEPHENS< STEVENS?
I don't understand the question. How does decimal notation relate to these names? Stephens comes before Stevens alphabetically; so that could make it less. However, Stephens is longer than Stevens; so that could make it greater.
A butcher in the market is 5'-10" tall, slim, brown eyes, short light hair and works out. What does he weigh
A doctor gives TTH six pills and tells her to take one every half an hour. How long will the pills last
A group of A2K'ers have been on vacation so long, that they've forgotten the day of the week. The following conversation ensues.
Mark: What's the day? I don't think it is Thursday, Friday or Saturday.
TehMeh: Well that doesn't narrow it down much. Yesterday was Sunday.
TTH: Yesterday wasn't Sunday, tomorrow is Sunday.
Thoh: The day after tomorrow is Saturday.
Stormy: The day before yesterday was Thursday.
Try: Tomorrow is Saturday.
Miss mi: I know that the day after tomorrow is not Friday.
If only one person's statement is true, what day of the week is it
: Monday
A doctor gives TTH six pills and tells her to take one every half an hour. How long will the pills last
I thought up quite a few ways to do this, but ultimately I went through this process. I looked for what each person would have said if they were telling the truth....
Interpreting the question in a different way yields the result: 2 and a half hours before TTH runs out!
You both have short memories. Remember - Mark doesn't lie.
Mismi is not saying today isn't Friday. She's saying today isn't Wednesday.
Therefore, Mark is the only one telling the truth. Today is [size=7]Wednesday[/size].
Better than: 1000000 = MM = Man March 
I told you Mark doesn't lie.
At 1 pm D (who was in the back) lost his paddle but did not tell M.
At 2 pm M looked back, saw that D did not have a paddle and punched him upside his head, which made D lose his straw hat.
The paper was under a door and we were each side of it?
Although how you got Mark to move is a riddle, because he is a super fit squash player!
Mark (M) and Dutchy (D) can paddle a canoe together in still water at 5 mph.
M alone paddles at 2 mph, D alone paddles at 3 mph.
At 12 noon they start paddling together down the river, which flows at 1 mph.
At 1 pm D (who was in the back) lost his paddle but did not tell M.
At 2 pm M looked back, saw that D did not have a paddle and punched him upside his head, which made D lose his straw hat. Then M gave his paddle to D who paddled upstream to the lost paddle.
Immediately after retrieving the paddle, they turned downstream and paddled together until they reached D's hat at (what time)
Note: Both the lost paddle and the hat floated with the current.
This was too hard in my head, my brain was too busy visualizing Mark punching Dutchy in the head
2^10=1024, so 2^1999 is roughly 10^600. 1999^2 is roughly 410^6. Observe that 10=log2^1024 < log2^1999 < log2^2048=11. Hence the third number is between 10^10 and 10^11.
What went wrong?
