Enumerati elementele urmatoarelor multimi: a) A={x/x este numar natural si x mai mic sau egal decat 8};; b:)B= {x/x este numar natural par si x mai mic decat 17};;,c) C={x/x este numar natural impar si 15 mai mic sau egal cu x mai mic decat 25

Answer 1

A={x | x∈N, x≤8}

x≤8

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

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

B={x | x∈N, x par, x<17}

x<17

x={0,1,2,3,4,...,16}

x par⇒

x={0,2,4,6,8,10,12,14,16}

B={0,2,4,6,8,10,12,14,16}

C={x | x∈N, x impar, 15≤x<25

15≤x<25

x={15,16,17,...,24}

x impar⇒

x={15,17,19,21,23}

C={15,17,19,21,23}
