Question

If A= { 1,8,2 } find the SUBSETS OF SET A​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Subsets of A are

A₁ = {} or Φ

A₂ = {1}

A₃ = {2}

A₄ = {8}

A₅ = {1,2}

A₆ = {1,8}

A₇ = {2,8}

A₈ = {1,2,8}

These are the 8 subsets of A

We can verify that with a formula

Formula of Subsets of A = 2ⁿ

where n = number of elements in A

here, n = 3

So, Subsets of A = 2³ = 8

Hence Verified!!
