    \$\begingroup\$ That's a very vague rule. I may decide that the square root of 1, the square root of the square root of 1, etc. are all different approaches and I have an infinite number of answers. Is a+b different from b+a? Is (-a) * (-b) different from b * a? \$\endgroup\$ Commented Sep 24, 2014 at 8:18

    \$\begingroup\$ I am aware of this, but I cannot represent 4^(4^(4^(4^4))) in any regular number format – storing 4^(4^(4^4)) as an integer already needs more bits than there are atoms in the universe). So unless I use a computer algebra system capable of handling such numbers (if one exists at all), I need to treat these as special cases. This however almost certainly requires more characters than I win by overkilled. Therefore these awards are pointless unless you somewhat exclude multiple square roots. \$\endgroup\$ Commented Sep 24, 2014 at 18:42
