square root of 9 = 3 but 2, 17 and 23 are irrational numbers
It could be either. For example, √9 is a rational number, whereas √2 is not.
Yes. The square of a whole number is always a whole number. For example, 3 squared is 9, so the square root of 9 is 3. What you never have, is the square root of a whole number being a fraction that is not a whole number. The square root of a whole number is either a whole number or an irrational number. For example, the square root of 2 is irrational, because there are no 2 whole numbers a and b such that a/b squared is 2. This is not terribly difficult to prove, but I have already said too much; I have answered your question.
an irrarional number is a number that can't be written as a fraction or whole number. -sqrt(9)=-3 This is a whole number so it isn't irrational, just rational
3 is the square root of 9. 9 is a square number. 9 is the square root of 81. 81 is a square number.
The square root of 9 is rational.
No.
Yes. The square root of any number that is not a perfect square (like 9 or 36) is irrational.
The square root of 9 is 3 which is rational.
The square root of 9 is a rational number. This is because the square root of 9 is equal to 3, which can be expressed as a fraction, 3/1. In general, a rational number is any number that can be expressed as a ratio of two integers, which is the case for the square root of 9.
No. The square root of 81 is 9, which is a rational number.
Because 9 is a perfect square - which means that its square root is an integer. 3 is not a perfect square.
The square root of 9 is 3 which is a rational number
no square root of 9 is 3 which is rational -- to be more specific: an irrational number is a number that cannot be expressed as a fraction. Pi, for example, is one of these numbers. If a number is not a perfect square (4, 16, 9, 144, 225, etc.), then it's square root is likely to be an irrational number. For example, the square root of 2 (1.41421356...) is an irrational number because it cannot accurately be expressed as a fraction.
It is not a real number.
It is none of those because the square root of -9 is an imaginary number but the square root of 9 is 3 which is a rational integer or whole number
The square root of 9 is irrational
