No, it is rational.
No.
The square root of 9 is rational.
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 a rational number
The square root of 9 is 3 which is rational.
No. The square root of 9 is 3. An irrational number is a number that can't be expressed with a fraction, meaning it is not an integer or a whole number. Numbers such as pi or e are irrational. Rational numbers are numbers that can be expressed with a fraction. Hope this helps!
It is not a real 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 all of them except for irrational.
The square root of 9 is 3 which is a rational number
No, the square root of an irrational number is not always rational. In fact, the square root of an irrational number is typically also irrational. For example, the square root of 2, which is an irrational number, is itself irrational. However, there are exceptions, such as the square root of a perfect square of an irrational number, which can be rational.
No. The square root of 81 is 9, which is a rational number.
