Question 1093543
<br>Without some context or any instructions and what this notation means or what we are supposed to do, this problem is meaningless.  If you want help with it, you need to tell us what it means and what we are supposed to do with it.<br>
If this is the complete problem as it was given to you, then it does not involve mathematics at all -- it only involves a guessing game, trying to figure out what the author of the problem meant.<br>
Re-post with an explanation if you are serious about getting help with this.
