I got one!

With 5 eight's, and 5 basic operators (+, -, *, /, ^, plus parenthesis, of course.), is it possible to get the numbers 1 - 16 (It may be no, 16 is arbitrary ;) )?
If so: how, and how far can you go (continuously after 10)?


E.X.
(8/8)^8-(8/8) = 0


jonbush asked a very good question:
Quote from: jonbushSo we must use all five 8's, but we can use any number of operators?


Yes. NO OPERATORS/OPERATIONS NOT MENTIONED!


And no programs to try every single combo, either. Fine... I used one myself to solve it anyway...


And if you do create a program, you need to explain (prove, in short) why that particular one is impossible... :ninja:

Edit: big numbers are as big as floats will allow. I do not know how floats behave when overflowing.

Also, technically you could use the minus sign as a negation, and not subtraction  :P

No solutions: 3,5,12,13,14 (On the off chance i missed something, please correct me :P )

Edit 3:
Apparently i cant use RPN to genarate a list of all possible combinations... that sucks :( )

Amazing. Perhaps check "Don't use smileys? as 8) turned into 8)


I got an answer for
3: [spoiler] 8/8+(8+8)/8 [/spoiler]
5: [spoiler] 8-(8+8+8)/8 [/spoiler]
12: [spoiler] 8+8*8/(8+8) [/spoiler]
14: [spoiler] 8+8-(8+8)/8 [/spoiler]
Credits to PT_ ^^
And the longest continuous string of numbers that can be produced using this method is: [spoiler]13: 0-12, but you could do negatives.[/spoiler]







I got another one, and it's even more tedious.


If you have 4 of the numbers 1 - 9 (excluding 4, that makes this pointless), and you can only use one of the same type per equation, what numbers can you NOT express using only:
(), +, - (or negative), /, ^, sqrt(), nth-root(), and factorial.
1-200 is required, but -500 to 500 for brownie points! (yay)


I tested this out, and it is rather cool.

I know it's not allowed but for the five 8's problem, if you use natural logarithms and cube roots...

[spoiler=very hacky stuff ahead]
...
ln(ln(cuberoot(cuberoot(cuberoot(cuberoot(cuberoot(cuberoot(8)))))))/ln(8))/ln(8+8/8)=-3
ln(ln(cuberoot(cuberoot(cuberoot(cuberoot(8)))))/ln(8))/ln(8+8/8)=-2
ln(ln(cuberoot(cuberoot(8)))/ln(8))/ln(8+8/8)=-1
ln(ln(8)/ln(8))/ln(8+8/8)=0
-ln(ln(cuberoot(cuberoot(8)))/ln(8))/ln(8+8/8)=1
-ln(ln(cuberoot(cuberoot(cuberoot(cuberoot(8)))))/ln(8))/ln(8+8/8)=2
-ln(ln(cuberoot(cuberoot(cuberoot(cuberoot(cuberoot(cuberoot(8)))))))/ln(8))/ln(8+8/8)=3
...

[spoiler=pretty print! But it include 3's]







[/spoiler]

and so on. Just add a cube root for every 1/2 and there you go, every integer ever.

[spoiler=please disqualify me already]

I might not disqualify you; that's pretty clever.  (-_(//));
*disqualifies juju*
oops...  :-X

Meh. Your images aren't working for me, btw. Perhaps also find a super cheaty way to solve my second problem?

Here are the answers of your first question, I've checked every number <= 50, and the ones that are not in this list, are impossible to solve:

[spoiler]1:  (8-8)*8+8/8
2:  (8+8)/(8*8/8)
3:  8/8+(8+8)/8
4:  (8+8+8+8)/8
5:  8-(8+8+8)/8
6:  (8*8-8-8)/8
7:  8*8/8-8/8
8:  8*8*8/8/8
9:  8*8/8+8/8
10: (8*8+8+8)/8
11: 8+(8+8+8)/8
12: 8+8*8/(8+8)

14: 8+8-(8+8)/8
15: 8+8-(8/8)^8
16: (8*8)/((8+8)/8)
17: 8+8+(8/8)^8
18: 8+8+(8+8)/8

23: 8+8+8-8/8
24: 8+8+8+8-8
25: 8+8+8+8/8

32: (8+8)*(8+8)/8

40: 8+8+8+8+8

48: 8*(8-8/8)-8[/spoiler]
