Answer 2

Answer:

Step-by-step explanation:

What are Irrational Numbers?

$\textbf{The numbers which are}$

$\textsf{1. Non Terminating}$

$\textsf{2. In roots}$

$\textsf{3. Have Bars on them}$

$\textbf{If the number fulfills the criteria , it is an it is an Irrational Number.}$

$\huge\textsf{FOR EXAMPLE:-}$

$\textsf{Let us say an irrational number say root2 }$

$\textsf{If we divide it in decimals we get 1.41424142....}$

$\textbf{And it continues}$....

$\textbf{We can also see that it continues and never ends}$$\textsf{And never ending numbers are called NON TERMINATING NUMBERS}$

Another point is if we see this it is also written as 1.1412 bar .

$\textsf{So it is bar number also}$

$\huge\textbf{OBSERVATIONS}$

$\textsf{Root 2 is Fulfilling all the criterias above}$

$\strong\textbf{Hence Root 2 is an Irrational Number}$

Rational Numbers:-

The numbers which are terminating and are also considered in whole number and maybe they appear in Fractions are Rational numbers.

For Example 2,3,4,5, 1/2 etc.
