SUMMARY

The discussion focuses on determining if the number 2 is part of the set defined as {x∈R|x is the square of an integer}. Participants clarify that this set includes all real numbers that can be expressed as the square of an integer. Since 2 cannot be expressed as the square of any integer, it is concluded that 2 is not a member of this set.

The question is, "determine whether 2 is a set of the following," the set being
{x∈R|x is the square of an integer}

I think I might need a bit of help interpreting the meaning; I believe its saying that if you square some number, you'll get x, right? I just need a little help reading this.
