Hello all you GMAT lovers out there! Im a long time lurker, first time poster....I saw a question with the below and was a bit confused by it and was wondering if any of you smart people out there could lend me a helping had.

If N^2 is an integer wouldn't N have to be a Integer as well? I mean a fraction times itself would always be a fraction, so if N^2 is a intiger so should N, right? This is contradictory to what the OG is saying....

Thanks for your help!!!!

sqrt 3 is not an integer. Thats what is implied here. N could be the sqrt of an integer and still not an integer

I also had the exact same doubt ! Thanks for posting this..

Now its clarified.

the other way round is correct.

If N is an integer then \(N^2\) should be an integer. Might be obvious but just mentioned here.
