Question

Complectati adecvat:
a)daca a ∈ {-17,8: 0; 9/11; -21,(4); -9/11}, atunci I a I ∈ {.....................}

b)daca a ∈ {2,93; -3; 15/4; 7 intreg 2/3; -8, atunci I a I ∈ {....................}

Answer 1

a) |a| ∈ { 17,8; 0; 9/11; 21,(4); 9/11}
b) |a| ∈{2,93; 3; 15/4; 7 intreg 2/3; 8}
astai tot

Answer 2

a)daca a ∈ {-17,8: 0; 9/11; -21,(4); -9/11},
atunci I a I ∈ {17,8 ; 0 ; 9 /11 ; 21,(4)  ;  9 /11 }

b)daca a ∈ {2,93; -3; 15/4; 7 intreg 2/3; -8,
 atunci I a I ∈ {2,93  ; 3 ; 15 /4  ; 7 intreg2/3  ; 8 }
