Thanks in advance!

Thank you for the opportunity to help you with your question!

A={x|x^2=7}

^2 means power two

Please let me know if you need any clarification. I'm always happy to answer your questions.

I know that, I'm just not sure how it would be written in roster notation!

A={x|x^2=7}

this is the roster form

Wouldn't that be set notation? Roster form is without the x|x so it would just be a roster list of numbers like {1,2,3,4}?
