would it be 4√50x^6

Hmm. I don't know what the answer would be. Let me solve it.
$$\sqrt{(200x )^{7}}=200x^{7/2}$$
I don't even know how you would go about simplifying this some more - I think this is as far a you can go, or if I went about it the right way.

Is it (200x)^7 or 200(x^7)?

the first one right after "Let me solve it"

question: how do you get a nice square root symbol like that with superscript exponents and everything ..do you copy and paste from something?

sorry.. i got that wrong... $$10*\sqrt{2*x ^{7}}$$
just click equation.. then you can insert this stuff or learn the syntax.. it's pretty easy.. ^^

$$\sqrt{200x^7}$$
$$=\sqrt{4\times25\times2}x^7$$
$$=10\sqrt{2x^7}$$
$$= 10(2x^{7/2})$$

Use your equation editor at the bottom of your comment box, a little hard to use at first.

10$$\sqrt{200x^7} = \sqrt{100*2*x^6*x} = 10*\sqrt{2}*x^3\sqrt{x}$$
