Answer 2

To find the set difference A\B, you need to remove all elements from set B that are also present in set A. In other words, A\B will contain all the elements that are in set A but not in set B.

Given:

A = {1, 5, 8, 7} B = {1, 3, 7}

To find A\B, follow these steps:

1. Remove all elements from B that are also in A.
2. The remaining elements in A will be the result.

Let's do it step by step:

Step 1: Remove common elements from B that are also in A. B\A = {3}

Step 2: The remaining elements in A are the result. A\B = {5, 8}

So, A\B = {5, 8}. These are the elements that are in set A but not in set B.
