What is the subset of AB?

Assuming that you mean the Cartesian product of two sets A and B by the notation A*B, if |A|=m and |B|=n, i.e., A and B have m and n elements respectively, a subset of A*B is a set containing none/some/all of the elements of A*B and if an element is in it, it must be an element of A*B (by definition of a subset).

Is AB a subset of B?

A-B means the set of all elements which are in A but not in B. A-B therefore does not contain any element in it which is not in B.

Is a is a subset of B then?

Step-by-step explanation: In mathematics, a set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B.

How do you prove that A equals to B?

Here’s how it works:

1. Assume that we have two variables a and b, and that: a = b.
2. Multiply both sides by a to get: a2 = ab.
3. Subtract b2 from both sides to get: a2 – b2 = ab – b.
4. This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a – b) and factor out b from the right side to get b(a – b).

When A is a subset of B and B is a subset of a then the two sets are?

Proper Subset: If A and B are two sets, then A is called the proper subset of B if A ⊆ B but B ⊇ A i.e., A ≠ B. The symbol ‘⊂’ is used to denote proper subset. Symbolically, we write A ⊂ B.

What type of sets are set A and set B if they have at least one common element?

Two sets that have at least one common element are called overlapping sets.

What is the subset relation?

The subset relation is a relation between sets. Now the elements of $A$may be sets, but you didn’t specify anything about them]

What do the sets A and B have in common?

Theintersection of A and B,writtenA\\B,istheset of all elements that belong to both A and B. This is what the two sets have in common. Below is a venn diagram illustrating the set A\\B.

What if A and B are two subsets of U?

Can a relation have different properties in different sets of ordered pairs?

And a relation (considered as a set of ordered pairs) can have different properties in different sets. For example, the relation R = {<1,1>, <2,2>} is reflexive in the set A1= {1,2} and nonreflexive in A2= {1,2,3} since it lacks the pair <3,3> (and of course it nonreflexive in N). Symmetry.
