    Fixed the quote. I don't see any reason why not, although it may well be less than currently. Either way, I have to get there first!

    I don't know. I feel reasonably strong at STEP now (Managed 6 full solutions in an hour to a mock earlier) but I also feel that there are a fair few users here equal to or stronger than I am mathematically.

    That's not even funny
    The most I've done is about 7/8 in 3 hours.

    Depends what type of parents honestly :P My mum went insane when I got a few B's and C's at GCSE Lol, along with my A*'s in media but those don't really matter.

    If they are likely to get disappointed, I'd just tell them now tbh, to either add shock value to if the results come out good, or to ensure they don't lose their **** on the day.

    How about . . .
    Prove that: \sqrt[3]{5} is irrational?

    *shamefully searches for the definition of irrational*

    I'll give it a go, oh ok so it can't be written as a fraction, seems simple enough

    LOL, so I have to prove that its a surd or w/e with no calculator right?

    Its irrational if it cant be written as a fraction right?

    Your calculator won't prove it's a non-terminating decimal

    My god! I should just walk away before even trying as I'd not be able to compete against your ability, let alone enough to get a 2 or even a 3 :-/ Its all starting to look like a dream again.

    Can't be written as the ratio of two integers.
    E.g \dfrac{\pi}{2} is an irrational fraction

     \sqrt[3]{5}=5^\frac{1}{3}
    That doesn't help much.
    Play around for a bit, and if you're not getting anywhere I'll give you a hint

    Assume the cube root of 5 is rational. Then we can write:

     5 = \frac{a^3}{b^3} where a and b are integers in their simplest form

     5b^3=a^3

    Clearly, a must be divisible by 5. This then means that the RHS has 3 factors of 5, and so the b must be divisible by 5. But then the fraction a/b can be simplified (indefinitely), which is a contradiction and so the cube root of 5 must be irrational.

    I'm sorry, I didn't mean to put anyone off. Besides, it's not a competition.
