QuestionМатематикт $a$ нь $A$ олонлогийн элемент мөн бол $a \in A$ , элемент биш бол $a \notin A$ гэж тэмдэглэх ба үүнийг $а$ элемент А олонлогт харьяалагдана ( харьяалагдахгүй ) гэж уншина. $A$ олонлог нь сөрөг тоон олонлог бол 45 гэсэн тоо $A$ олонлогт харьяалагдах уу? харьяалагдахгүй юу?

Studdy Solution

STEP 1

Assumptions
1. The set $A$ is defined as the set of negative numbers.
2. The number we are examining is 45.
3. We need to determine if 45 is an element of the set $A$ .

STEP 2

Recall the definition of the set $A$ . Since $A$ is the set of negative numbers, any number that is an element of $A$ must be less than zero.

STEP 3

Examine the number 45. Determine if it is less than zero.

STEP 4

Since 45 is greater than zero, it is not a negative number.

STEP 5

Conclude that 45 does not satisfy the condition to be an element of the set $A$ , which consists only of negative numbers.

STEP 6

Therefore, 45 is not an element of the set $A$ , and we denote this as $45 \notin A$ .

STEP 1

Assumptions1. The set A A A is defined as the set of negative numbers.2. The number we are examining is 45.3. We need to determine if 45 is an element of the set A A A.

STEP 2

Recall the definition of the set A A A. Since A A A is the set of negative numbers, any number that is an element of A A A must be less than zero.

STEP 3

Examine the number 45. Determine if it is less than zero.

STEP 4

Since 45 is greater than zero, it is not a negative number.

STEP 5

Conclude that 45 does not satisfy the condition to be an element of the set A A A, which consists only of negative numbers.

STEP 6

Therefore, 45 is not an element of the set A A A, and we denote this as 45∉A 45 \notin A 45∈/A.
