    Ok, so you want to solve:

    I := \displaystyle\int 5^{4y} \ dy

    We make the substitution, x(y) = 5^{4y}. Then we can write: \log(x) = 4y\log(5) \implies \dfrac{1}{x}\dfrac{dx}{dy} = 4\log(5) \implies dy = \dfrac{dx}{4x\log(5)}. Substitution into I yields:

    I = \displaystyle\int \dfrac{1}{4\log(5)} \ dx = \dfrac{x}{4\log(5)} + C which, upon the inversion back to a function of y means that:

    \boxed{I = \dfrac{5^{4y}}{4\log(5)} + C}

    I did it in degrees too. Apparently we may get some marks...

    You may; it all depends on the leniency of the mark scheme. As a side note I must say that I used radians in the examination. With answer I meant answer to the comment.

    Think I got 60/75. High B or a low A?
    I would say low A. The paper wasn't very hard but it was rather long and there were lots of places where you could make silly mistakes. But that's just my feeling.
