Question

How many subsets does set A have if the set A has 3 elements?
3
6*
8
is this the correct answer

Answer 1

If the set \(A\) is finite, then it has \(2^{|A|}\) in its power set.

Answer 2

Maybe you are forgetting about the entire set, and the empty set?

Answer 3

{a,b,c}
the is subset are {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}, {}

Answer 4

if n is the no. of elements
then no. of subsets=\[2^n\]

Answer 5

im confused

Answer 6

if a set has \(10 \) elements then its power set has \(2^{10}\) elements

Answer 7

no. of elements in the set=3
no. of subsets=\[2^3\]

Answer 8

if a set has \(4\) elements then its power set has \(2^4\) elements.

If a set has \(3\) elements, then its power set has \(2^?\) elements

Answer 9

oh so it would be 3

Answer 10

read what we wrote.

Answer 11

\[2^3=2*2*2=?\]
