संकल्पना:

एक समुच्चय A का घांत समुच्चय (या Powerset) स्वयं समुच्चय और शून्य या खाली समुच्चय सहित समुच्चय A के सभी उपसमुच्चयों के समुच्चय के रूप में परिभाषित किया गया है।

गणना:

दिया, A = {x, y, z}।

एक समुच्चय A का घांत समुच्चय (या Powerset) स्वयं समुच्चय और शून्य या खाली समुच्चय सहित समुच्चय A के सभी उपसमुच्चयों के समुच्चय के रूप में परिभाषित किया गया है।

A का घांत समुच्चय = {\(\rm \phi\),x, y, z, {x, y}, {y, z}, {x, z},{x, y, z}}

इसलिए, A के घांत समुच्चय में उपसमुच्चयों की संख्या 8 है।
