Now that we are beginning to get the hang of these...
Fill in the operators for the following equation. You may use any operators you wish. There should be at least three different ways to solve this equation.
4 4 4 4 4 4 4 4 4 = 2000
Typical operations that may be used include multiplication, division, addition, subtraction, exponentiation, square roots, factorials, and parens for grouping. Additionally you can squeeze numbers together, so using the above equation, 4, 44, and 444 (to name a few) would be legal.

I take it this is illegal?
4+4+4+4+4+4+4-4-4 = 20+0+0

You are correct, it is not legal. The equation must evaluate to 2000.

Perhaps more satisfying...
(444-44)*( (sqrt(4)*sqrt(4)) + (4/4) )

How about (4*4^4) + (4*4^4) - 44 - 4

An easier approach : 4*(444 + 44) + 44 + 4

Hopefully this one's OK
(4 ^ 4) * (4 + 4) - (4 * 4 * (4 - 4 / 4))

Here is another one.
(4! + (4/4)) *4 *(4+4+4+4+4) = (24+1)*4*20 = 2000
