I am assuming you want to apply PEMDAS operations to the numbers 3, 5, and 7 to get a final value of 33. Since it was not specified, I'm further assuming that any of the numbers can be used more than once.
One solution is (5+7)*3 - 3
By PEMDAS (Order of operations: Parentheses, Exponentiation, Multiplication, Division, Addition, Subtraction), since 5+7 is contained within parentheses, it is calculated first
5+7 = 12
This sum is then multiplied by 3 to get 12*3 = 36.
Finally 3 is subtracted from the product to get 36 - 3 = 33.
There may be other solutions
