# Math Help - Quantifiers

1. ## Quantifiers

Hi
Does anyone can help me to get the correct solutions for those problems? Thanx

2. Hello,

(i) True. Let x=1. There are no y, z satisfying x>y^2+z^2.
(ii) True. For all u, you can always find some v such that u+v is a square.
(iii) False. When u=w, no x satisfies u>wx and no v satisfies w>uv.

Bye.
