For example, arg(1/2^(1/2+12*I) , if you use Maple or Mathematica or by hand you can expand this BUT, actually the expression is quite cumbersome and tricky.
The proper answer is 2*Pi - 12*log(2). But that answer does not appear at fist hand, the <12> comes from an operation with { } and [ ]. ...
Using Maple 17: (1/2^(1/2+12*I)); convert(%, exp); argument(%); -12*ln(2)+2*Pi
