Is 2 an irrationa lnumber?

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.
