Insert ∈ or ∉ in each blank to make the resulting statement true. 6 _____ {3, 4, 5, 6}

검증된 단계별 안내

Understand the problem: We need to determine whether the number 6 is an element of the set {3, 4, 5, 6}.

Recall the meaning of the symbols: The symbol \( \in \) means "is an element of," and \( \notin \) means "is not an element of."

Look at the set \( \{3, 4, 5, 6\} \) and check if the number 6 is listed inside the curly braces.

Since 6 appears in the set, the correct symbol to use is \( \in \), indicating membership.

Write the complete true statement: \( 6 \in \{3, 4, 5, 6\} \).

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Set Membership (Element of a Set)

Set membership refers to whether a specific element belongs to a given set. The symbol '∈' denotes that an element is a member of the set, meaning it is included within the set's listed elements.

Set Notation and Symbols

Set notation uses curly braces {} to list elements, and symbols like '∈' and '∉' to indicate membership or non-membership. Understanding these symbols is essential to correctly interpret and complete statements about sets.

Evaluating Membership Statements

To determine if an element belongs to a set, compare the element with the set's listed members. If the element matches any member, use '∈'; if not, use '∉'. This evaluation is fundamental in set theory problems.
