Question

Scrieti elementele multimilor : A = {x | x ∈ N, x = 2k + 1, k ∈ N, k ≤ 3} B = {x | x ∈ N, x = 2↑k, x = 2↑k ∈ N, k < 4} C = {x | x ∈ N°, 2↑x ≤ 32} D = {x | x ∈ N°, x↑4 ≤ 64}. Ajutor plz

Answer 1

1) K=0,1,2,3 de unde A={1,3,5,7} 2) k=0,1,2,3 de unde B={0,2,4,6} presupunand ca simbolul acela e inmultire, ce reprezinta acea sageata? 3) 2x <=32, x <=32:2, x <=16 C={1,2,3,......,16} 4) x*4 <=64, x<=64:4, x <=16 D={1,2,3,....,16}
