Answer 5

Answer 6

\[\forall x \in R > 0\] is wrong isnt it?

Answer 7

I would rather use R_+

Answer 8

i know of that but that hasnt been introduced anywhere earlier. i guess the actual question is how to place more than one condition on a range?

Answer 9

\[\forall{x}\in\Bbb{R},x\ge0\]

Answer 10

does that not say "for all real x , x must be greater than zero ?

Answer 11

By itself, maybe, but it's not meant to stand alone.

Answer 12

so this makes sense?

\[\forall x, x>0 \text{ }\exists y \in R, y >0 : y^2 = x\]

Answer 13

i havent done much of this stuff, started the other day

Answer 14

\[\forall{x}\in\{x\mid x\in\Bbb{R}\land x\ge0\}\]... maybe?
