You can use the digits 1,2,and 3 once only and any mathematical symbols you are aware of, but no symbol is to be used more than once. The challenge is to see if you can make the smallest positive number.
Special rules: You cannot use Euler's number or pi or infinity.
Special thanks to: Rhonda Wendel for Make the most of these digits and for the problem text which was slightly altered.
THat would be:
lim(log x) , where x1+ (that means from the upper side of 1)
instead of log one can use a logarithm with base 3 or 2, since log may be considered to have base 10, and so is not in accordance with the rules.
