Question

C = { x/2 / x ∈ Z; 4 ≤x ≤12 ∧ x=(12) ̅ }
C = {}

Answer 1

Respuesta:

{3,4,5,6,7,8} = {x ∈ Z : 3 ≤ x ≤ 8} = {x ∈ N : 3 ≤ x ≤ 8}. 25. {..., 1. 8 ... Suppose A = {1,2,3,4} and B = {a, c}. ... Sketch the set X = {(x, y) ∈ R2 : 1 ≤ x2 + y2 ≤ 4} on the plane R2 ... 8c3 +12c2 +6c+1 = 2(4c3 +6c2 +3c)+1 would be odd, not even.
