Make 24 using exactly three 3s
Each number formed with a 3 and the 24 in the equation are all base 10.
You cannot introduce any additional digits or constants.
Plus(+), negation/subtraction (-), division(/ or show it with a fraction bar), multiplication(* or use grouping symbols as appropriate), exponentiation(^ or show it with an exponent). regular factorial(!), square root(sqrt(), or the radical symbol), grouping symbols such as parentheses and/or square brackets, and the regular decimal point(not for the repeating decimal) are allowed. No concatenation of any type is allowed.
No other functions/operators are allowed. This includes floor and ceiling functions not being allowed. (edit)
I am looking for a total of 10 solutions.

@ Weather Vane - Let us say that by adding the square root symbols, you have not changed the values of those. They are redundant. It's similar to writing 1! instead of 1 or 2! instead of 2. Although mathematically correct, I would not see them as "primitive solutions."

$(sqrt3)^3! -3 = 24$
Which is obviously only slightly different to hexomino's:

@ Rupert Morrish - Good, your first one listed is a definitely newer type, because, for instance, if the square root symbol were to be dropped, the expression would have a different value.
$endgroup$
– Olive Stemforn
May 22 at 21:50
$begingroup$
@OliveStemforn: But the order of powers (which square root basically is) is unimportant (ie $a^b^c = a^c^b$) so are these two really different? To me it feels like it is the same principle as $3times3!+3!$ being different from $3!+3times3!$ - its exactly the same operations, just in a slightly different order...
$endgroup$
– Chris
May 23 at 15:15
$begingroup$
@chris The order of powers is definitely important. $2^3^5 ne 2^5^3$ The first is $2^3^5 = 2^243$. The second is $2^5^3=2^125$. Perhaps you mean $(a^b)^c = (a^c)^b$.
$endgroup$
– Trenin
May 23 at 17:34

@Chris Because that is more applicable to this case anyways because $sqrt3^3!= (3^3!)^frac12=(3^frac12)^3!=(sqrt3)^3!$.

I feel like something should be able to be done with
$frac(3!)!30 = 24$
with judicious use of
decimal points
but I can't find it.
$frac(3!)!3^3 + 3 = 24$
uses 4 3s.

@ Weather Vane - Let us say that by adding the square root symbols, you have not changed the values of those. They are redundant. It's similar to writing 1! instead of 1 or 2! instead of 2. Although mathematically correct, I would not see them as "primitive solutions."

Tenth solution from hint
$$left(3+(3-3)!right)!$$

Thank you for this tenth solution. Is it not ironic how relative the lack of complexity this solution has, given the amount of time between its posting and the original problem?

$(sqrt3)^3! -3 = 24$
Which is obviously only slightly different to hexomino's:
(i) $sqrt3^3! -3 = 24$

@ Rupert Morrish - Good, your first one listed is a definitely newer type, because, for instance, if the square root symbol were to be dropped, the expression would have a different value.

@OliveStemforn: But the order of powers (which square root basically is) is unimportant (ie $a^b^c = a^c^b$) so are these two really different? To me it feels like it is the same principle as $3times3!+3!$ being different from $3!+3times3!$ - its exactly the same operations, just in a slightly different order...

@chris The order of powers is definitely important. $2^3^5 ne 2^5^3$ The first is $2^3^5 = 2^243$. The second is $2^5^3=2^125$. Perhaps you mean $(a^b)^c = (a^c)^b$.

@Chris Because that is more applicable to this case anyways because $sqrt3^3!= (3^3!)^frac12=(3^frac12)^3!=(sqrt3)^3!$.

I feel like something should be able to be done with
$frac(3!)!30 = 24$
with judicious use of
decimal points
but I can't find it.
$frac(3!)!3^3 + 3 = 24$
uses 4 3s.

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
