Dad's joke. How many equations that you can solve?

What about 8?

2+2+2
3*3-3
4+4-sqrt(4)
5+(5/5)
6+6-6
7-(7/7)
8-sqrt(sqrt(8+8))
9-(9/sqrt(9))

I do these every day in my math class at school I love these we did one today where we had to use 5 4s to make 13 and I came up with an answer that my teacher Haden's seen all through the past 6 periods I felt so proud

2 + 2 + 2 = 6
3 * 3 - 3 = 6
Square root of 4 + Square root of 4 + Square root of 4 = 6
5 / 5 + 5 = 6
6 - 6 + 6 = 6
7 - ( 7 / 7 ) = 6
Cube root of 8 + Cube root of 8 + Cube root of 8 = 6
9 - ( 9 / square root of 9 ) = 6
