How can you fill in the parentheses with the numbers $1, 3, 5, 7, 9, 11, 13$ to make the above equation true? Repeats are allowed, but you must fill in all of the parentheses!
Bonus if you already solved this:
Can you do it without extra symbols? (no +, -, ÷, ｘ, <<, !, etc.)
(EDIT: You don't have to use all of the numbers.)
EDIT2: Okay, the answer is not that there is no answer. I'm not looking for a mathematical proof here.
EDIT3: The above information is all you need to solve the problem. Be creative!
