The correct Answer is:
To solve the problem of identifying whether the sets G and H are disjoint or overlapping, we will follow these steps: ### Step 1: Define the Sets We need to define the sets G and H based on the given conditions. - **Set G**: G = { x : x = 8n, n ∈ N and n < 7 } - **Set H**: H = { x : x = 9n, n ∈ N and n < 7 } ### Step 2: Determine the Elements of Set G We will find the elements of set G by substituting values of n from 1 to 6 (since n is a natural number less than 7): - For n = 1: x = 8 * 1 = 8 - For n = 2: x = 8 * 2 = 16 - For n = 3: x = 8 * 3 = 24 - For n = 4: x = 8 * 4 = 32 - For n = 5: x = 8 * 5 = 40 - For n = 6: x = 8 * 6 = 48 Thus, the elements of set G are: \[ G = \{ 8, 16, 24, 32, 40, 48 \} \] ### Step 3: Determine the Elements of Set H Next, we will find the elements of set H by substituting values of n from 1 to 6: - For n = 1: x = 9 * 1 = 9 - For n = 2: x = 9 * 2 = 18 - For n = 3: x = 9 * 3 = 27 - For n = 4: x = 9 * 4 = 36 - For n = 5: x = 9 * 5 = 45 - For n = 6: x = 9 * 6 = 54 Thus, the elements of set H are: \[ H = \{ 9, 18, 27, 36, 45, 54 \} \] ### Step 4: Compare the Sets Now we will compare the elements of sets G and H to determine if they are disjoint or overlapping. - Set G: { 8, 16, 24, 32, 40, 48 } - Set H: { 9, 18, 27, 36, 45, 54 } ### Step 5: Identify Overlapping or Disjoint Sets We check if there are any common elements between sets G and H. - The elements of G are: 8, 16, 24, 32, 40, 48 - The elements of H are: 9, 18, 27, 36, 45, 54 Since there are no common elements between the two sets, we conclude that: **G and H are disjoint sets.** ### Final Answer G and H are disjoint sets. ---
