Yes. i.e. 1 and 0. Usually not though
The square root of 1 is 1.The square root of 0 is 0.
It is if the number is more than ' 1 '. If the number is less than ' 1 ', then it's smaller than its own square root.

If the square root of a number is irrational, it is its own conjugate. sqrt(13)*sqrt(13) = 13 and you no longer have an irrational!
The square root of -81 is an imaginary number, specifically 9i, where i represents the imaginary unit equal to the square root of -1. Since the square root of -81 does not result in a real number, it is considered irrational. Rational numbers are those that can be expressed as a ratio of two integers, whereas irrational numbers cannot be expressed in this form.
Well, honey, let me break it down for you. The number 31 is not a square number because it cannot be expressed as the product of an integer multiplied by itself. So, in simpler terms, you can't find a whole number that you can multiply by itself to get 31. Keep on crunching those numbers, darling!
52 = 25Root 25 = 525 - 5 = 20

The number 5 plus the square root of 7 is irrational. A number is considered rational if it can be expressed as a ratio of two integers, while an irrational number cannot be expressed in this form. Since the square root of 7 is not a perfect square and cannot be simplified to a rational number, the sum of 5 and the square root of 7 is irrational.
