Allow me to explain the (possibly not obvious) reason why this fails.

Tracey is right with her answer, barring the "always" statement regarding rational and irrational. There is an exception, and that would be Pi squared, which remains irrational.)
At first glance, I thought the test makers had it wrong, (the mathematical sentence is correct) when I saw her next comment was wrong, which I would call a trick question because only half of the problem is wonky. And of course, the commenters on the blog where this was posted LOL'd about "hahaha, women and math = fail!" and then continued to comment on how the actual MATH was wrong.
(1.4142135623730950488016887242097 + 2.8284271297461900976033774484194)2 = 18. :D
HEY TEENAGE BOY:
FAIL.
