Some square roots are rational but the majority are not.
Only if the square root of the numerator and the square root of the denominator are both rational numbers.
Yes. The square root of 81 is 9 - a natural number and all natural numbers are rational numbers.
The square root of 169 is 13, which is a whole number. Since whole numbers are considered rational numbers (they can be expressed as a fraction with a denominator of 1), the square root of 169 is rational.
They are NOT rational numbers, so the question is misguided.
The square root of 81 is 9, which is a whole number. Since all whole numbers are considered rational numbers (as they can be expressed as a fraction with a denominator of 1), the square root of 81 is rational.
Yes, the square root of 1.21 is a rational number. The square root of 1.21 is 1.1, which can be expressed as a fraction (11/10). Since rational numbers are defined as numbers that can be expressed as a fraction of two integers, 1.1 qualifies as rational.
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.).
The square root of 61.93 is irrational. Since rational numbers are infinitely dense there cannot be a closest rational.
Because numbers such as pi, e and the square root of 2 are not rational.
Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
There are no rational numbers between sqrt(-26) and sqrt(-15). The interval comprises purely imaginary numbers.
