Answer: 1.41421356237..
The decimal expansion of the rational number is either ending or non-terminating. As a result, we can confidently conclude that a rational number’s decimal expansion can be continued by terminating or non-terminating.
If the result of taking the square root of a number is not a perfect square, then the result is an irrational number.
Irrational numbers are numbers that cannot be written in the form of a fraction in any way. Irrational numbers have decimal expansions that do not terminate and do not recur at any point in the expansion.
The number 2 is a rational number.
The decimal expansion of 2 is non-repeating and non-terminating.
