C={x apartine A|x=b^3,b apartine N}.ENUMERATI ELEMENTELE MULTIMILOR A,B,C. DAU COROANA!!!!!!

Answer 1

Răspuns

Explicație pas cu pas:

A={x|x=2^n.nE N,n<4}

n = 0, 1, 2, 3

x = 1, 2, 4, 8

A = {1, 2, 4, 8}

___________

B={x apartine A|x=a^2,apartine N}

B = {1, 4}

___________

C={x apartine A|x=b^3,b apartine N}.

C = {1, 8}
