Answer 1

Answer:

Irrational Number

Explanation:

A number is said to be rational if it can be expressed in the form a/b (where b is not equal to zero), a terminating or repeating decimal.

If a number cannot be expressed in any of the forms above, it is said to be Irrational.

The number:

$\sqrt{20}$

cannot be expressed in any of the forms of a rational number, therefore, it is an Irrational Number.

NOTE:

Integers are positive and negative whole numbers (including 0).

Natural numbers are whole numbers starting from 1.
