Question

Write the subsets of the set A={2,3,5}

Answer 1

The subsets of set A are:

{ (),(2),(3),(5),(2,3),(2,5),(3,5),(2,3,5) }
Total eight subsets.



Shortcut to find number of subsets:
${2}^{n}$
where n = no.of elements in a set.

Applying this shortcut in the above set,
n=3

$= {2}^{3} = 8$

Answer 2

Given,

set A={2,3,5}

To Find,

The subsets =?

Solution,

We can solve the question as follows:

It is given that we have to write the subsets of the set A={2,3,5}.

$A =$ {$A,B,C$}

The number of subsets of a given set is equal to 2 to the power of n where n is the number of elements in the set.

$No.\; of\: subsets\: in\: a\: set = 2^{n}$

Where, $n = Number\: of\: elements$

Since set A has three elements, the number of subsets will be:

$= 2^{3}$

$= 8$

Therefore, the subsets will be:

{2}, {3}, {5}, {2,3}, {2,5}, {3,5}, {2,3,5}, {} (empty set).

Hence, the subsets of set A are {2}, {3}, {5}, {2,3}, {2,5}, {3,5}, {2,3,5}, {}.
