Step-by-step explanation:

it is rational

Answer 2

Answer:

(i) 23 is not a perfect square values so that, it is an irrational number. The decimal expansion of above number is terminating, so that it is a rational number. The decimal expansion of above number is non-terminating recurring, so that, it is a rational number.

We can't write 23 as square of some number

So $\sqrt{23$ is not the perfect square.

Hence it is an irrational number

MEANING :

                  A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).
