Which elements in the set below are integers? –3, 3.7, √ 81 , –7.34, √ 8 , 5, 56⁄7, –1 a. –3, √ 81 , 5, 56⁄7, –1 b. 3.7,√ 81 , √ 8 , 5, 56⁄7 c. –3, 3.7, –7.34, –1 d. 3.7, –7.34, √ 8

The answer is:  A. –3, , 5, .

The explanation is shown below:

1) By definition, the integers include whole numbers, negative numbers and zero.

2) Therefore, keeping this information on mind, you have that:

-3 is a negative number without decimal part, therefore, it is an integer.

3.7 is decimal number, so it is not an integer.

(It is a whole number, therefore, it is an integer).

-7.34 is a decimal number, so it is not an integer.

is an irrational number. It is not an integer.

5 is a whole number, therefore, it is a integer.

(It is a whole number, then, it is an integer).
