Question

Dados los conjuntos: U = {x/x ∈ N ; 5 ≤ x ≤ 13} A = {x/x ∈ Z ; x < 10} B = {x/x ∈ Z ; 7 < x < 39} halla: n(A∩B)

Answer 1

Respuesta:

n(A∩B) = { 8,9 }

Explicación paso a paso:

U= { 5,6,7,8,9,10,11,12,13 }

A= { 0,1,2,3,4,5,6,7,8,9 }

B= {8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38 }

n(A∩B) = { 8,9 }
