Answer: 32
Step-by-step explanation:
When the set has n elements, the power set has [tex]2^n[/tex] elements. This also gives us the cardinality of the power set, which is what we are looking for.
A = {2,3,9,7,5}
(1) 2
(2) 3
(3) 9
(4) 7
(5) 5
n = 5
[tex]\displaystyle 2^n[/tex]
[tex]\displaystyle 2^5[/tex]
32
