Question

1. misal A = {1, 2, 3} dan B = {2, 1, 5} maka (A gabungan B) - A.
2. jika H = {2, 4, 5} K = {1, 4, 7} dan L = {7, 5, 1} maka (H - K) irisan L.

bwserta jalannya ya

Answer 1

1. A={1,2,3}
B={2,1,5}
A U B= {1,2,3,5} - {1,2,3}
= {5}

2. H={2,4,5}
K={1,4,7}
L={7,5,1}

{2,4,5} - {1,4,7}= {1,2,5,7} Irisan {7,5,1}
= {2}
