The square root of a composite number is not always an irrational number. e.g. 4 is a composite number and its square root is 41/2 = 2, which is rational number.
No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.
The square root of 61.93 is irrational. Since rational numbers are infinitely dense there cannot be a closest rational.
No. Square roots of whole numbers that don't result in whole numbers (e.g. the square root of 64 is 8), are considered to be "irrational numbers".
Since it is the square root of a negative number, it is actually imaginary, neither rational nor irrational. It is equal to 9i, or 9 times whatever the square root of negative one is.square root of -81 = square root of 81 times i = 9i

Only if the square root of the numerator and the square root of the denominator are both rational numbers.
Some square roots are rational but the majority are not.
Yes. The square root of 81 is 9 - a natural number and all natural numbers are rational numbers.
They are NOT rational numbers, so the question is misguided.
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).

Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
Because numbers such as pi, e and the square root of 2 are not rational.
There are no rational numbers between sqrt(-26) and sqrt(-15). The interval comprises purely imaginary numbers.
