4 sixes make a 30?

I'm fond of this simple one: $6 \times \left(6 - 6\div 6\right) = 30.$

What about not using an operation between the first two sixes?

66 - 6 x 6 = 30

$\Gamma(6-6/6)+6$ where $\Gamma(n)=\int_{0}^\infty \left(t^{n-1}e^{-t}\right)dt=(n-1)!$

6*6-(6/sgn(6)) = 30,

Where sgn(x) represents the signum function.

How about this one: 6 x 6 - 6 + {6} = 30

Where { } stands for fractional part of given number..

$(6\times\sqrt{6\times6})-6 = 30$

$(6-\log_6 (6))×6$

6*(6-(6/6))

Hey the easiest method is to.
(6-6÷6)6 =30

6^0 * 6*6-6

6 X (6 - 6 / 6)=30

6 x (6 - 6/5) = 30

Can you have 6^2 +6 -6 -6 = 30 ?

((6!/6)/6)*6

(6-(6/6)) x 6= 5 x 6 = 30

6x6 - sqrt(6x6)

The simplest solution seem to be 6(6-6÷6)=30

66-6x6 ! --> that's an exclamation mark, not a factorial sign...

Here is also a simple one:

6-6+(6^2-6) =30

6^2 - 6 + (6 - 6)

(6 \times 6 -6) \times 6^{0} =30

((Sqrt(6 x 6)) x 6) - 6
