Question

मान लीजिए कि A = {1, 2} और B = {3, 4}. A × B लिखिए। A × B के कितने उपसमुच्चय होंगें? उनकी सूची बनाइए।

Answer 1

A × B = {1, 2} × {3, 4}
= {(1, 3), (1, 4), (2, 3), (2, 4)}
A × B के उपसमुच्चयों की संख्या = 24 = 16
A × B के उपसमुच्चयों के अवयव = h, {(1, 3)}, {(1, 4)}, {(2, 3)}, {(2, 4)}, {(1, 3), (1, 4)}, {(1, 3), (2, 3)},{(1, 3), (2, 4)}, {(1, 4), (2, 3)}, {(1,4), (2,4)}, {(2, 3), (2, 4)}, {(1, 3), (1, 4), (2, 3)}, {(1, 3), (1, 4), (2, 4)}, {(1, 3), (2, 3), (2, 4)}, {(1, 4), (2, 3), (2, 4)}, {(1, 3), (1, 4), (2, 3), (2,4)}
