Question

If A= { x: x is a natural number divides 12 } find the numbers of element in p(A)

Answer 1

Answer:

= 1,2,3,4 and 6 are the only natural numbers which

divides 12.

= Therefore, number of elements in a set is 5.

= Numbers of elements in p(A)= 2^n, where n is number of elements in set.

=2^5

=32

Here, number of elements in p(A) is 32.
