Question

Descrieti in cuvinte, cat mai exact fiecare dintre multimile urmatoare:

A={1,2,3,...,60,61};   B={3,4,5,6,...9,10,11};       C={1,11,111,1111,...};
D={2,4,6,8,...30,32,34};                     E={71,73,75,77,...101,103};;

 - Scrieti doua multimi similare si descrieti-le in cuvinte.

MULTUMESC, IMI TREBUIE DE URGENTA!!!

Answer 1

Numerele :1,2,3,...,60,61 apartin multimii A.
Numerele: 3,4,5,6,...9,10,11 aparin multimii B.
Numerele:1,11,111,1111... apartin multimii C.
Numerele: 2,4,6,8,...,30,32,34 apartin multimii D.
Numerele: 71,73,75,77,...,101,103 apartin multimii E.

Doua multimi similare sunt: F={11,22,33,44,...,88,99}=Numerele:11,22,33,44,...,88,99 apartin multimii F.G={90,100,110,120,...,180,190}=Numerele:90,100,110,120,...,180,190 apartin multimii G.
