Answer 2

Answer:

The number of subsets is 8 .

Step-by-step explanation:

Given:

A set which is given in the question is $A = {1,4,5}$ .

To Solve:

We need to find out the subset of this set.

Subsets are a part of the mathematical concept of sets. A group of items or components which are enclosed in curly braces, such as $\{a, b, c, d\}$ is a set. Set B is referred to as a subset of set A if it contains the elements $\{2,4,6\}$and set A is a collection of even numbers.

Here the number of elements is $3$ .

So $n=3$

The formula of subset is $A=2^n$

Put the value in the above subset formula .

$A=2^n\\= > A= 2^{3} \\= > n= 8$

Therefore the number of subset is $8$ and the subsets are $\phi,\{1\},\{4\},\{5\},\{1,4\},\{4,5\},\{1,5\}$ and $\{1,4,5\}$ .
