Question

Which elements in the set are integers? –8, 3⁄4, √ 18 , 0, √ 16 , 5, –2⁄7, 6

Answer 1

`-8,0,√(16) ,5,6`

Explanation:

The integers are the set of positive and negative whole numbers.

`-8` is an integer because it is a negative whole number.

`(3)/(4)` is not an integer, it is a rational number.

`√(18)=√(9*2)=3√(2)`

`√(18)` is not an integer because it cannot simplify to a whole number

`0` is an integer because it is a whole number.

`√(16)=√(4^2)=4`

`√(16)` is an integer because it simplifies to a whole number.

`5` is an integer because it is a whole number.

`-(2)/(7)` is not an integer, it is a rational number.

`6` is an integer because it is a whole number.
