Use two 8s and two 3s to make the number 24
$begingroup$
Use two $8$s, two $3$s, and basic arithmetic operators ($ +, -, times , div$, parentheses) to make the number $24$.
(You may not join numbers together to form new numbers, like $ 8, 3rightarrow 83$)
I don't know how to start besides just trying to find the correct answer. Is there a way you can make this equation through small steps or I should just bruteforce it?

Please clarify: what operations can be used? Addition, subtraction, multiplication, division? Can we concatenate numbers? Etc, etc.

If I am not mistaken, this question is not asking people to solve the puzzle in question, but is instead asking strategies for how to go about solving it beyond just trying things at random.

Here is a solution that uses only "elementary" operations (addition, subtraction, multiplication, and division).
$8 div (3 - (8 div 3))$ (or alternatively $frac{8}{3 - frac{8}{3}}$)
$= 8 div frac{1}{3}$
$= 24$
If we allow square roots, a simpler solution is possible.
$sqrt{8 times 8 times 3 times 3}$
$= 8 times 3$
$= 24$
In fact, there are many more solutions if you allow more operations.
