or 3*2*2*2

Another one:

3^3-3

3^3-3

Yeah, I got 3 to the third power minus 3 too.

4! + 4-4

4 squared plus 4 plus 4

I got some for each number except 1:

((sqrt(2) * sqrt(2))^2)!

3^3 - 3

(3 + 3/3)!

4! - 4 + 4

(4 + sqrt(4)) * 4

(5 - 5/5)!

(sqrt(5) * sqrt(5))! / 5

((6 / .6) - 6)!

[7 * .7 - .7]!

sqrt(9)^sqrt(9)-sqrt(9)

(sqrt(9) + 9/9)!

9*sqrt(9)-sqrt(9)

(where [x] is floor x--the integer portion of x)

((sqrt(2) * sqrt(2))^2)!

3^3 - 3

(3 + 3/3)!

4! - 4 + 4

(4 + sqrt(4)) * 4

(5 - 5/5)!

(sqrt(5) * sqrt(5))! / 5

((6 / .6) - 6)!

[7 * .7 - .7]!

sqrt(9)^sqrt(9)-sqrt(9)

(sqrt(9) + 9/9)!

9*sqrt(9)-sqrt(9)

(where [x] is floor x--the integer portion of x)
