Hello Sir/Ma'am, course ke ander topic subtopic me jo practice question aur PYQS hai usme power wale term power me nahi ho raha hai, confusion ho raha hai ki wo term power me hai ya multiply me.
jaise image 2A show ho raha hai wo actual me 2 ke power me A hai. aisa lag raha hai ki 2 and A dono multiply me hai.
please resolve this problem as soon as possible.
thankyou.
@nikita.s ma'am mera doubt ye tha ki ush type ke question me kya (2ᴬ) aise show nahi ho sakta jisse pehchanne me problem na ho
@singhkaran1220 Dear Learner, Thank you for your query. In this question, 2ᴬ does not mean 2 multiplied by A. It is a notation used to represent the power set of A. The power set of a set A means the set of all possible subsets of A. For example, if A = {5, {6}, {7}} Then 2ᴬ (power set of A) will contain: ∅ (empty set) {5} {{6}} {{7}} {5, {6}} {5, {7}} {{6}, {7}} {5, {6}, {7}} Here, the small “A” written in power form (2ᴬ) does not indicate multiplication. It only represents the number of subsets, which is 2ⁿ where n is the number of elements in set A. So there is no multiplication involved — it is just mathematical notation for the power set.
