Hmm, it's not necessarily a question, sorry for the lapse of word choice.

I'll edit the attachment.

It just means z is an integer that is not divisible by any squares. (And this condition uniquely determines x,y,z.)

 

[leehuan]

It means perfect square when it says square.

So we can't use something such as sqrt(16) = 4

Or sqrt(32) = 4sqrt(2) ------> this case, z would have to be 2, not 32, using what glittergal said

Gotcha thanks,

So basically, root z cannot be equal to any real numbers?

Rational.

It can still be real. At your point in the course I don't think you've touched complex numbers yet.

Real numbers are basically anything that have no imaginary part, so pi and sqrt(3) etc. count.

Gotcha, thanks for the help!
