Question

7.
If A = {1,2,3,4,5,6,7} then number of elements in the power set of A is
1) 2^6
2) 2
3) 2^7

4) 2^8​

Answer 1

Answer:

$Option \green {(3)} \:is \: correct$

Step-by-step explanation:

Given Set A = {1,2,3,4,5,6,7}

Number of elements in set A = n = 7

$Number \: of \: elements \: in \: power\: set\\ =n[P(A) ]= 2^{n}\\= 2^{7}$

Therefore.,

$Option \green {(3)} \:is \: correct$
