No. The square roots of 2, 3 and 5, for a start, are not rational.
No. The square roots of perfect squares are rational.
The square root of a rational number is not always rational. While the square root of a perfect square (like 1, 4, or 9) is rational, the square root of non-perfect squares (like 2 or 3) is irrational. Therefore, not all square roots of rational numbers yield rational results; only those of perfect squares do.
No, they are not.
No. Relatively few square roots are.
Yes. Both square roots of 36 are rational.
The square roots are irrational.
The square roots are rational.
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 any positive square number is always rational as for example the square root of 36 is 6 which is a rational number.
They aren't. The square roots of prime numbers are always irrational.
Some square roots are rational but the majority are not.
The square root of 16 is rational. The answer would be 4, so, yes; they can be rational.
Square root of a rational number may either be rational or irrational. For example 1/4 is a rational number whose square root is 1/2. Similarly, 4 is 4/1 which is rational and the square root is 2 which of course is also rational. However, 1/2 and 2 are rational, but their square roots are irrational. We can say the square root of a rational number is always a real number. We can also say the rational numbers whose square roots are also rational are perfect squares or fractions involving perfect squares.

No. The square roots 8 are irrational, as are the square roots of most even numbers.
No, they are not.
