Answer 1

Imaginary complex real

Answer 2

1) 5 = Natural, Integer, Rational, Real

2)
`√(2)` = Irrational, Real

3)
`(7)/(13)` = Rational, Real

4)
`5i` = Imaginary , Complex

5) 0 = Integer, Rational, Real

Explanation:

We have to find the categories that the number falls into.

So first we define the terms,

Natural number - The positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.

Integers number - A whole number; a number that is not a fraction.

Rational number - A number that can be in the form p/q , where p and q are integers and q is not equal to zero.

Irrational number - A number that cannot be in the form p/q , where p and q are integers and q is not equal to zero.

Real number - A real number is a whole number, rational and irrational but not imaginary and infinity.

Imaginary number - When squared a number, gives a negative result represent as
`√(-1)=i`.

Complex number - It is a combination of a real Number and an imaginary Number.

Now, categories the number

1) 5 = Natural, Integer, Rational, Real

2)
`√(2)` = Irrational, Real

3)
`(7)/(13)` = Rational, Real

4)
`5i` = Imaginary , Complex

5) 0 = Integer, Rational, Real
