    Are you sorted out yet?

    I did it without using quadratics. Perhaps it was a bit of a long way but we arrived at the same answer.

    No I really don't get it. *see picture above*
    I hope it's just a small mistake in my workings or something, but I can't see where I'm not following the rules properly.

    Well done! You underestimate yourself.

    Your error is that when you multiply through by 2, the 1 needs doubling as well!

    After that, forget y-substitution, the other method works just fine.

    I've spotted a few other trivial errors on your working sheet. Such as when you use the log(4) x - log(4) x^2 = log(4) x/x^2 rule, the base only appears once! Also, you needn't substitute at all, as 2log(a) x - log(a) x is, of course, 1 log(a) x

    Am having trouble seeing enough of the picture at the right size for me to be able to see properly so I can't check your workings, sorry.

    Try starting it off like this, for a change:

    log2(x) + 1 = log4(x)
    log2(x) + log2(2) = log4(x)
    log2(2x) = log4(x) (y = y)
    log2(2x) = y rearrange to find 2x
    log4(x) = y rearrange to find x


    See if you can solve from there.

    I find it slightly funny in an ironic that you're mocking other peoples mathematical ability. :rolleyes:

    That disappointing moment when you realise that you're more gifted than a substantial part of TSR's Cambridge prospects.
