still not convinced, you are saying $\lim a^b = (\lim a)^{(\lim b)}$. Your supposedly justification does not do the job.

@Henry i am sorry, i am asking about (ii). I do not understand how it is different to (iv), maybe it is not. I would like an independent confirmation. I was meant to say 1,3,4 are easy...
