    was 6a the surd one, if it was it got 2 root 11
    I got that too, I meant the one about "find the equation of the axis of symmetry" and also the one with indices where you had to solve for n.

    YASS! I wrote a little paragraph where I went off on a tangent () explaining why x couldn't be 1. Time well spent haha...

    No I got that one, I'm talking about the (2)^n = 1/64 one, something like that?
    I got n= -2, cos the first answer was 64, and I thought if it was a negative power you put 1 over it, therefore getting 1/64...? :confused:

    Also (n/2)x(n/2+1) for the second last one. The last one I got 2550 = 50x51

    So was the question:

    2^n = \frac{1}{64}, find the value for n?

    If so, it'd be -6. But I get the feeling that's not what it asked.
