Question

b. Sean los conjuntos X = {10; 20; 30:40)y Z = {5; 10; 15; 20), calcula n(X x Z).​

Answer 1

Datos:

X = {10; 20; 30:40)

Z = {5; 10; 15; 20),

calcula n(X x Z).

Solución:

X x Z = {(10,5);(10,10),(10,15);(10,20);(20,5);(20,10);(20,15);(20,20);(30,5);(30,10);(30,15);(30,20);(40,5);(40,10);(40,15);(40,20)}

n(X x Z)= 16 elementos
