Answer 1

Question:

Identify the sets that contain 2 as an element. (Check all that apply.)

$A.\ \{2, 3, 4, 5, ...\}$

$B.\ \{0, 1, 4, 9, ...\}$

$C.\ \{2, \{2\} \}$

$D.\ \{\{2\}, \{\{2\}\}\}$

$E.\ \{\{2\}, \{2, \{2\}\}\}$

$F.\ \{\{\{2\}\}\}$

Answer:

$A.\ \{2, 3, 4, 5, ...\}$

$C.\ \{2, \{2\} \}$

Step-by-step explanation:

Required

For which of the options is 2 an element

$A.\ \{2, 3, 4, 5, ...\}$

The elements of this set starts from 2, then 3 and continues as thus.

Hence: 2 is an element

$B.\ \{0, 1, 4, 9, ...\}$

From the given elements in the above set, 2 is not listed.

Hence: 2 is not an element of this set

$C.\ \{2, \{2\} \}$

Here, 2 is listed as an element, 2 is also listed as a subset.

Since 2 is listed as an element, then 2 is an element of the set.

$D.\ \{\{2\}, \{\{2\}\}\}$

Here, 2 is listed as a subset of {2} and also as a subset of subset of {{2}}.

Since 2 is not listed as an element itself, then 2 is not an element of the set.

$E.\ \{\{2\}, \{2, \{2\}\}\}$

Here, 2 is listed as a subset of {2} and also as a subset of subset of {2,{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set

$F.\ \{\{\{2\}\}\}$

Here, 2 is listed as a subset of subset of {{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set
