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.

No.

Because 9 is a perfect square - which means that its square root is an integer. 3 is not a perfect square.

No. The square root of 81 is 9, which is a rational number.

The square root of 9 is 3 which is a rational 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

It is rational.The square root of 9 is 3 and it is a rational number

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!

The square root of 9 is irrational

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.

Square root of 75 is about 8.660254038 so it is 9

square root of 9 = 3 but 2, 17 and 23 are irrational numbers

the square root of 82

The square root of 9 is 3 which is a rational number

It is all of them except for irrational.

No because the square root of 81 is 9 which is a rational number

If the square root of a natural number is not an integer, then it is irrational. Another way to look at it: if a natural number N falls between two perfect squares, then the square root of N is irrational.So in this case, 12 is between 9 (3 squared) and 16 (4 squared). So the square root of 12 is between 3 and 4, and also the square root of 12 is irrational.

The square root of 9/16 is 3/4 which is a rational number

It is an irrational number because it can't be expressed as a proper fraction

no. it is 9

If you mean the square root of 9/36 then it is 1/2 otherwise the square root of 936 can't be simplified because it's an irrational number

For example, in the case of integers: the square root of a positive integer is either an integer (in the case of perfect squares, such as the square root of 1, 4, 9, 16, etc.), or an irrational number (such as the square root of 2, 3, 5, 6, etc.). Similar in the case of the square root of a rational number (fraction): if you don't specifically choose fractions with perfect squares in the numerator and denominator (e.g., 4/9), you will end up with an irrational square root.

No because the square root of 9 is 3 and 3 times 0.4 is 1.2 which is a rational number
