No, because the square root of 3 is an irrational number

The square root of 3 is an irrational number

No. 3 is not a perfect square, so its square root is irrational.

The square root of 3 is not a rational number because it can't be expressed as a fraction.

The square root of 12 is not a rational number. In fact, it is a radical number. It's simplified form would be 2 multiplied by the square root of 3.

No.

Yes, because the answer is 3/2 which is a rational number.

Yes because the square root of 0.09 is 0.3 or 3/10 which is a rational number.

No.

Its 3 which is a rational number

Yes 3 is a rational number

Yes, the square root of 3 is a real number. (It is not imaginary. The square root of a negative number is imaginary.) The square root of 3 is not a rational number. It cannot be written as a fraction.

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

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

Surds are irrational numbers and 27 is a rational number but if you mean the square root of 27 then it is an irrational number and expressed as a surd it is 3 times square root of 3.

no the square root of 9 is 3 which is rational since it can be written as 3/1. remember a rational number is any number that can be written as a/b where a and b are integers.

No, the square root of 3 is not rational.No. The square root of 3 is irrational.More generally: if p is a prime number then the square root of p is irrational and the proof of this fact mimics the famous proof of irrationality of the square root of 2.No - the square root of 3 is not rational, but the proof is too involved to post here.

is the square root of 3 rational

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

It depends on the number whose square root is being taken.sqrt(4)/3 is rational but sqrt(5)/3 is not.

No. The square root of most numbers is irrational - only if the number of which you take the root happen to be perfect squares, do you get a rational root. In this case, to take the square root of 3/4, 3 is not a perfect square, so the root is not rational. Or you can take .75 to be 75/100; once again, 75 is not a perfect square, so the root is irrational.
