    A simple question I know, but I don't understand the answer on the mark scheme (it seems wrong to me)
    Given that p=log23 and q=log25, find expressions in terms of p and q for:
    a) log245
    b) log20.3

    Now I can do part a, but the mark scheme says that the answer to part b) is p-q-1
    How can this be right?

    a) 2p +q
    b) log23/(5*2) = log23 - log25 - log22
    = p-q -1
