Is that from an edexcel C1 past paper? Because I'm pretty sure that was the first question of my C1 exam.


Or from a higher tier paper at GCSE.

No, you got the 16x16x bit right, but it's x−1/44x^{-1/4^{4}}, which is the same as x4×−1/4x^{4\times -1/4}.I think you need to be more careful with your bracketing - I would consider x−1/44x^{-1/4^{4}} to be the same as x−1/256x^{-1/256}, not (x−1/4)4(x^{-1/4})^4
