Solution

Break Down the Problem

  1. We are given the statement AB{2,3} A \cap B \supseteq \{2, 3\} .
  2. We need to determine if this implies {2,3}A \{2, 3\} \subseteq A and {2,3}B \{2, 3\} \subseteq B .

Relevant Concepts

  1. The intersection AB A \cap B consists of all elements that are in both sets A A and B B .
  2. The notation \supseteq indicates that the left side is a superset of the right side.

Analysis and Detail

  1. The statement AB{2,3} A \cap B \supseteq \{2, 3\} means that both elements 2 and 3 are in the intersection of A A and B B .
  2. If both 2 and 3 are in AB A \cap B , it follows that:
    • 2 is in both A A and B B .
    • 3 is in both A A and B B .

Verify and Summarize

  1. From the logical deduction, since both elements (2 and 3) are present in the intersection AB A \cap B , it confirms that:
    • {2,3}A \{2, 3\} \subseteq A
    • {2,3}B \{2, 3\} \subseteq B

Final Answer

True. The statement AB{2,3} A \cap B \supseteq \{2, 3\} implies that {2,3}A \{2, 3\} \subseteq A and {2,3}B \{2, 3\} \subseteq B .
