Make N N N equal to 6 where N is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Question

Using standard mathematical symbols, (i.e. no other letters or numbers), make the following true:

As a freebie, I will give the easiest away, 2 + 2 + 2 = 6

All numbers are base 10...

Possible duplicate of 6, the magic number - I should've known it was asked before. — Glorfindel, May 24 '19 at 11:25
Drat, I was completely unaware... I tried every possible combination of searches to verify the possibility of a duplicate and came up with nothing... @Glorfindel I've given you a vote up to help ease the pain... — Eliseo D'Annunzio, May 27 '19 at 01:27

Some variations:

(0! + 0! + 0!)! = 6
(1 + 1 + 1)! = 6
2 + 2 + 2 = 6
3! - 3! + 3!= 6
√4 + √4 + √4 = 6
5 / 5 + 5 = 6
6 + 6 - 6 = 6
7 - 7 / 7 = 6
8 - √(√(8 + 8)) = 6
√9 * √9 - √9 = 6

And an other minimalist solution (for computer folks)

0 + 0 + 0 != 6
1 + 1 + 1 != 6
2 + 2 - 2 != 6
3 + 3 + 3 != 6
4 + 4 + 4 != 6
5 + 5 + 5 != 6
6 + 6 + 6 != 6
7 + 7 + 7 != 6
8 + 8 + 8 != 6
9 + 9 + 9 != 6

If you add two spaces after each spoilered line, the formatting will work as intended. – Glorfindel May 24 '19 at 11:25
I hadn't considered 3! - 3! + 3!, nice variation! – Eliseo D'Annunzio May 24 '19 at 11:26

Here you go:

(0! + 0! + 0!)! = 6
(1 + 1 + 1)! = 6
2^2 + 2 = 6
3 * 3 - 3 = 6
√4 + √4 + √4 = 6
5 + 5 / 5 = 6
6 + 6 - 6 = 6
7 - 7 / 7 = 6
8 - √(√(8 + 8)) = 6
√9 * √9 - √9 = 6

(for those of you unfamiliar with the !, it's the factorial)

Definitely well thought out. I pretty much had the same answers when I was first presented with this puzzle a while back. Well done. – Eliseo D'Annunzio May 24 '19 at 11:24
