~Enigmas / Problems~

Hi
I thought we could make a topic with some enigmas, so as to make our brain work a bit.

here is the first one :

?IX=VI

whats the missing symbol? (ie, ?=...)


another one, more difficult :

You gotta do : 24
You have the numbers : 1 5 5 5
You must use these numbers once and once only
You can use : +; -; *; /;

5 x 5 = 25
25 - 1 = 24

or we must use all number ?^^

25 - 1 = 24

^_^

5 x 1 / 5 x 5 +5 + 5 - 1 x 5 / 1 x 5 x 1 x 5 - 5 - 5 - 5 x 1 / 5 x 1 x 5 x 5 + 1 + 1 + 5 / 4 = 24 !!!!!!!

seriously I will think on it ^^

I'm not sure about the first one. As in what you're exactly given and whatnot.

IX = 9 and VI = 6 but any ? wouldn't work...

5 5 5 1

1/5 = 0.2

5-0.2 = 4.8

4.8*5 = 24

Next.

i have one find the number y!!

1 3 9 27 81 x x x x x x x x x x x x x x x y

but fiZ is it only number enigmas or can i put textual enigmas?

im quite impressed for the second one
here is the next, more difficult imo :

you have : 1 5 6 7
you must do : 21
same rules
lets say im gonna give 10fg for the first guy who find it, so as to make it a bit spicy

as for the first, try not to be 'narrowminded' in someway :p

1 3 9 27 81 243 729 2187 6561 19683 59049 177147 531441 1594323 4782969 14348907 43046721 129140163 387420489 1162261467 3486784401

@tib : you can put textual enigmas aswell
(you can ask me if you want me to translate it ^^)

1/5=0.2
6/0.2=30
30*7=210 I did 21(0) xD

try again :p

@ Gthibault = Multiply by 3 so just raise to whatever power y is.

@ DarkoZ hmmmmmmmmmmmmm.
I keep getting 210 -_-.

i said it would be more difficult this time :p

ba let's try

3 6 30 210 630 1260 6300 44100 ?

maybe I gave to much indication

132 300

thats : *2,*5,*7,*3,, *2,*5,*7,*3 etc

Are you sure there's a solution for the latest one? The closest I've gotten is 210
