I've been asked to simplify and I don't know how.

1/[square root of 1/(square root of x+2) +2]

Wow.

Yes, you've stated the problem correctly. What's throwing me is the square root fraction w/in the square root - but then you probably know that's the hang up.

BTW, is there some way I can use the trick symbols that so many others use? It would make writing a problem clearer.

I'm getting a bit tired at this point, but you can see where this is going,

and maybe I'll get back to this later or someone else may complete it if

you have further problems (also check the algebra!!).

Hello, tesla1410!

I don't blame the Cap'n for tiring out.

I suppose they want it__completely__rationalized . . . *sigh*
