Find the derivative of $y=\sqrt{1+\sqrt{x}}$
I know it comes out to $$y' = \frac {1} {4\sqrt{x}\sqrt{1+\sqrt{x}}}$$
But have no ideas on how to get there or where to start.

Do you know the chain rule? Usually when you have to take a derivative of something of the form $f(g(x))$, that's where you start. The chain rule says that the derivative is $$f'(g(x))\cdot g'(x).$$
