a)fals
b)fals pt ca -2<-1
c)π≈3,1415
3,14 ∈ (3,4)
d)-π≈-3,1415
-3,1415 >-3,15
-3,1415<-3,14 =>-π∈(-3,15;-3,15) => adevarat
e)-√3≈ -1,732...
-1,732... ∉(-1,73;-1,72) => adevarat
f)adevarat
g)-2/3=-0,(6)
-0,(6)>-1
-0,6<+∞
=>-2/3 ∈ (-1;+∞)-adevarat
h)-√10≈ -3,1622...
-3,1622..<-3,16000....
=> -√10 ∈ (- ∞;-3,16) => fals
i)5/3=1,(6)
1,1(6)=1,16666
1,(6)=1,6666
=> 1,1(6)<5/3
si 1,1(6)>1
=> 1,1(6) ∈ (1;5/3)-adevarat
