No it's not
Step-by-step explanation:
2 could not have been made by squaring a rational number! This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number. In other words, the square root of 2 is irrational.

No.
Step-by-step explanation:
An irrational number:
- is a number that cannot be written as a fraction
- cannot be found by dividing two numbers
- cannot be expressed as a ratio between two integers
- does not terminate nor have a pattern
An example of an irrational number would be pi/π/3.14159 ...
The reasons why 2 is not an irrational number:
- it can be expressed as a fraction - i. e. : 2/1, 4/2, 12/6, etc.
- it can be found by dividing two numbers - i. e. : 2:1, 4:2, 12:6, etc.
- can be expressed as a ratio between numbers
- terminates and has a pattern
2 is also a natural number, whole number, real number, and integer.
