Find the Cardinality (2,0)

Problem

|(2,0)|

Solution

1. Identify the type of object provided. The expression (2,0) represents an ordered pair, which is a single element in a set (such as a point in the Cartesian plane ℝ2.

2. Define cardinality. The cardinality of a set, denoted by |S| is the number of elements contained within that set.

3. Treat the ordered pair as a set. If the task refers to the set containing this ordered pair, S={(2,0)} then the set contains exactly one element.

4. Determine the count. Since (2,0) is a single mathematical object, its cardinality as a set is 1.

Final Answer

|(2,0)|=1
