Little help please, I'm failing and need the extra credit and have no idea how to work these problems.

1. [tex]

x = \sqrt{30 + \sqrt{30 + \sqrt{30 + \ldots } } }

[/tex]

2. Find the 4th root of -1.

I know that this is the same thing as the square root of i. I also know that the answer is:

sqrt(i) = sqrt2/2 + sqrt2/29(i)

However, my teacher wants us to prove it obviously.
