Answer
Since the total of five 5s is 25, we have to choose an operator which can make a large number.Obviously, the multiplication operator is not good enough. We chose the factorial operator!
((5!+5!)-55)/5 = (120+120-55)/5 = 185/5 = 37
5!/(5+5)+5*5 = 120/10 + 25 = 12 + 25 = 37
A third solution uses "raising to the 5th power"
((5+5)/5)**5 + 5 = 37
