Question

Aflati multimile A= {x apartine N* | 2x + 4 < sau egal 12} si B = { y apartine N | 2 la puterea 3 < 3 la y < 2 la 7 } URGENTT !! multumescc

Answer 1

2x+4≤12⇒2x≤8⇒x≤4⇒x=[1,2,3,4];
⇒A=[1,2,3,4]⇒elementele multimii A;
2³=8;
2⁷=128;
⇒8<3 la y<128⇒y=[2,3,4];
⇒B=[2,3,4]⇒elementele multimii B;
