    is this the same as 5^2n+4 = 5^2 = 2n+4 = 2 ?

     5^{2n+4} = 25 \implies 5^{2n+4} = 5^2 \implies 2n+4 = 2

    It is correct, but you should have used brackets while writing the question.

    Thanks, what do you mean use brackets?

    Does logxy = logpd = xy = pd ?

    If the logs have the same base?

    I meant write  5^{2n+4} = 25 as 5^(2n+4)=25.

     logxy = logpd \implies xy=pd

    You are correct

    I realise you are typing and it is not as easy as using a pen, but your use of equals is wrong.

    How can 5^2 equal 2 ?

    To be honest, i was slightly disappointed to get 97, i wanted 100, but made a simple mistake in the paper.

    Though 97 are still great marks

    No.

    Getting 100% in C1 doesn't makes you anything, get 100% in STEP then i will say you are awesome.

    What marks did you get in all your other units and what is STEP?

    I was sensible enough to not expand 2^30.

    This was the question:  x(2x^{- \frac14})^4

    You look very optimistic about STEP, does anybody ever scores full in all STEP papers?

    If you do it your legacy on TSR will live forever!

    Have a look at my TSR profile, to see my marks.

    STEP is a difficult maths exam usually taken by students who want to study maths at cambridge/warwick.

    Aha Ah you need to get ones like that

    Oh no I'm completely putting it on here I'm not very optimistic and certainly not that optimistic I think there are usually a handful of people who get full marks or just drop 1 or 2 marks.
