    I hope the other half is overconfidence, then!

    just a thumbs up for a passing of information. You just got +350 experience points. Congratulations. Now stop being paranoid :P

    Close, but it should be a squared root. Not sure where you got the cubed root from.

    (continued from below) Now take all that and write it down with pencil and paper, using the fraction bar rather than the division symbol.

    No silly!!! Two hundred and forty three divided by two equals one hundred and twenty one and a half!
    I just separated the square root of two from that part of the equation. Therefore the complete expression is:
    Two hundred and forty two which multiplies the square root of two and is divided by two is equivalent to one hundred and twenty one and a half which multiplies ...

    243/2 = 121.5

    243/sqr(2) = 121.5*sqr(2)
    When simplifying expressions it is untidy to leave a square root in the denominator. what you do in that case is to multiply top and bottom by the same square root. In this case Sqr(2)/Sqr(2).
    (243/Sqr(2))*(Sqr(2)/Sqr(2)) =
    (243*Sqr(2))/2 =
    121.5*Sqr(2)

    (continuation from below) You may round it at the 4th decimal point or at the 500th, but you will need to round it at some point.
    In case you're being silly and using a calculator, those also round irregular numbers after a certain number of significant figures.
    If you want an unrounded solution you cannot simplify further than 121.5*Sqr(2).

    unfortunatelly you have to give a rounded answer if you want a single, decimal number here. Sqr(18) = Sqr(9*2) = 3*Sqr(2)
    (3^6)/(3*Sqr(2)) = (3^5)/Sqr(2) = (243*sqr(2))/2
    This equals 121.5 multiplied by an irregular number. So he answer, too must be irregular. Now the only way to write it as a single number would be to approximate the value of sqr(2). (continued)
