Question

EXERCITIUL DIN IMAGINE

Answer 1

A intersectat cu N= 2; 0; $\sqrt{16}$=4
A intersectat cu Z= toate nr de acolo
A intersectat cu Z₊=2; 0,(5);1/0,(3);$\sqrt{16}$
A intersectat cu Q= toate nr de acolo
A intersectat cuQ₋=-3;-1/2;-6/3;-3 5/6;-$\sqrt{36}$

Answer 2

0,(5)=5/9
-6/3=-2
1/0,(3)=1/(3/9)=9/3=3
-3INTREG 5/6=(3X6+5)/6=-23/6
√16=4
-√36=-6
A={2,-3,-1/2, 5/9, -2, 0, 3, -23/6, 4, -6}
AintersectatN={ 0,2,3,4}
A intersectat Z={-6,-3,-2,,0,2,3,4}
Ainters.Z(+)={0,2,3,4}
Ainters.Q={-1/2, 5/9,-23/6}
Ainters.Q(-)={-1/2, -23/6}
