Don't know... a few candidates for it?
Why does 1+1=2?
Prove, using only maths, that the meaning of life, universe and everything is 42.
Is a cow when it spins? (valid question)
'99 Q8 b (v) (under time limit of 3 hhours after you did the whole exam
formulate a similar resutl for a cyclic n-gon?
I have no idea. If I meet the hardest one I'll forget because I can't do it.

Hardest? Q8(b), 1989 (which not a single candidate was able to complete BTW).

Prove, using only maths, that the meaning of life, universe and everything is 42

Simple: 6 * 9 = 42

 

[BlackJack]

Let's post this question then:
1989 Q8 (b)
The difference between a real number r and the greatest integer less than or eual to r is called the fractional part of r, F(r). Thus F(3.45) = 0.45...

NO! I GIVE UP! Just reading it is a pain! Ugh!!! Who has time to do this in a 3 hr exam?!

I'm sure 6 * 9 give 42... *cough*

You obviously havn't read THE BOOK ....

 

[Lazarus]

Mr Adams later admitted that it was a mistake and that he meant to write 6 * 7, and you'll find that written in reprinted copies.

6 * 7 ? Well that makes no sense at all ...

 

[Mathematician]

Maybe

Maybe because 6 is regarded as evil and 7 is good.
Evil vs Good
Know what i mean?

Maybe this one.

Prove the Riemann hypothesis: The Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part ½:

[tywebb]

Douglas Adams may have thought it was 42, but nope it is ½.

how tf have u revived this thread

 

[tywebb]

Maybe we can look at other things like this:

Prove or disprove:




And why would that be hard? Because it is undecidable (can’t be proved or disproved) as shown in 1963 by Paul Cohen:
