Question

Va rog tare ajutaţima dau coroniţa censtit !​

Answer 1

Răspuns:

a)B⊄A

b)A⊂C

c)B∪C≠A

d)B∩C=A

e){2, 3, 6}⊂B∪C

Explicație pas cu pas:

A={x∈N|x:6 si x<50}⇒x∈M₆⇒A={6, 12, 18, 24, 30, 36, 42, 48}

B={x∈N|x:3 si x<50}⇒x∈M₃⇒B={3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48}

C={x∈N|x:2 si x<50}⇒x∈M₂⇒C={2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48}

(M₆=multiplii lui 6, M₃=multiplii lui 3, M₂=multiplii lui 2)
