Diketahui P = {x | 4 ≤ x < 10, £ bilangan asli } dan Q = { x | 7 < x < 13,x £ bilangan cacah }. Hasil dari P U Q adalah ...
pake cara!

Answer 1

P = {4, 5, 6, 7, 8, 9}
Q = {8, 9, 10, 11, 12}
P U Q = {4, 5, 6, 7, ..., 12}
semoga membantu :)

Answer 2

P={x|4<_x<10=4,5,6,7,8,9}
Q={x|7< x<13,x£=8,9,10,11,12}
PuQ={4,5,6,7,8,9,10,11,12}
