​

Answer 1

Answer:

hey root 2 is not a rational number

Step-by-step explanation:

because ,

A rational number is a number which can be written in p/q form where p and q are integers and q is not equal to zero.

For example 1/2 ,3/4 etc.....

and also root 4 is also a rational number as it can be as 2 and 2 can further be written as 2/1.

but root 2 cannot be written in p/q form where p and q are integers and q is not equal to zero

Therefore,root 2 is not a rational number.
