Agar set me 10 element ho to power set mein kitna element hoga ?

[@GATEWAY_MITHILESH_KR]

2^10 = 1024. Formula diya hua hai video me.

Sir, yeh belongs to aur subset of main kya antar hai? Aapne kaha rikt samuchay har ek samuchay ka upsamuchay hai.
Lekin rikt samuchay ker ek samuchay ka avyay nahi hai. Iska matlab thoda clear kr dijiye sir.

[@GATEWAY_MITHILESH_KR]

Agar ek set man le A = { 1 } hai... To set ke paribhasha ke anusar 1 belongs to A kahlaeyga. Jabki 1 subset of A hum nahi kah sakte. Lekin {} subset of A hamesa he hota hai.

N = {{{{}}}} k kitne power set honge?? Answer please.

[@MithileshKumar-kr6tp]

Yahan set mein sirf ek element hai.
Isliye power set 2^1 = 2 hoga.

[@GATEWAY_MITHILESH_KR]

Only 1

[@KARISHMAGUPTA-x6x]

power set = 2^n jahan n us set k elements hain. Agar question kuch aisa ho to..... power set of N = { {}, {{}}, a } = ??
Answer please?

[@MithileshKumar-kr6tp]

यहां सेट में तीन एलिमेंट है । तो घात समुच्चय होगा 2^3 = 8

[@GATEWAY_MITHILESH_KR]

Number of elements 3 hai.
Power set= 2^3= 8
