    but I can't get any further with getting e < 9/16

    Any help would be appreciated

    Can't see what the problem is. All I see is a warning of some kind!

    Can you tell me the whole question or what exam paper it's from, because I can't figure out how you get e < 9/16 from that!?

    According to the mark scheme
    http://www.edexcel.com/migrationdocu...s_20060616.pdf that should be:

    (4e+4)/25 > (4e-1)/5

    So, I'd suspect an error in your previous working.

    Right I've found the paper, and basically your inequality is wrong, it isn't

    "(4e+4)/25 > (4e-4)/5"

    it should be (4e+4)/25 > (4e-1)/5

    I can't tell you where your working went off, but you're slightly off.

    If you can't see where you went wrong then just reply and I'll show my working for you.
