Using only math symbols (no functions like sin, cos, log, etc.) create an expression with only two 2s equal to 5 (no other digits or constants).
(In reply to
re(3): perhaps?  spoiler perhaps. by Leonidas)
It says no functions like sin, cos, log, etc. I take that to mean functions that use letters to represent them. Math symbols, even those representing functions, are presumably allowed. In fact even + is a function, of two arguments. Thus my notation that sqrt would have to be written as a surd (radical) to qualify, rather than written as letters (as it was posted here because of the limitations of adding math symbols in a comment)
I'll try, however, with "view source"
