did not quite get the stem of the question due to the FUNNY char!!

Generally I do a PREVIEW before clicking the SUBMIT button.

Hey Enginpasa,

I am fairly sure that there's something wrong with those options. There is no way that the irrational number ROOT of 8, would get resolved into simple integers like you stated in your options.

Please let us know if those options are indeed correct.

Thanks!
For love, not money.

Yah, the question is definitely wrong.

Just estimating, 1/3 - root8 = approx .333 - 2.8 = approx -2.5

-2.5 squared is 6.25. None of the answers are even remotely close.
