Question about SET NOTATION.
What does it mean you see: x is an element of R^+

Answer 1

i think R^ is a power set. It's a set that contains all possible subset of a given set R

Answer 2

Do you mean \(\mathbb{R}^+\)?

Answer 3

Oh, missed that, :)

Answer 4

good job @KingGeorge

Answer 5

If that's the case, then it means that \(x\) is a positive real number. I.e., \(x>0\).

Answer 6

@KingGeorge. Yes

Answer 7

So then \(x\in\mathbb{R}\) such that \(x>0\).
