No. Though every perfect square is a rational number, not every rational number is a perfect square. Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.

The square root of 4 is 2. 2 is a rational number so they square root of 4 is rational.

No. The square of 4âˆš(2) is an imperfect square. But since it is = sqrt(2), it is not rational.

The square root of 4 is 2 which is a rational number

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.

The square of any rational number is also rational.

No, they are not.

The square root of 4 is 2 which is a rational number

(250)2 = 62,500 Yes, that's a rational number.

It is rational. The root of a perfect square, such as 4, is rational; the root of any positive integer that is not a perfect square is an irrational number.

The square root of 2, for example, is irrational.sqrt(2)*sqrt(2) = 2 which is rational.

√2.

Yes because the square root of 4 is 2 which is a rational number

The square root of 2 is an irrational number

that depends on the number. sqrt(2) is irrational, sqrt(4)=2 is rational

irrational

the square root of 2

No because it is 2 times the square root of 21 which is an irrational numberThe square root of 84 is not a rational number

No; the square root of any rational number squared is that rational number. Examples: √(2^2) = √4 = 2. √((1/2)^2) = √(1/4) = 1/2

Another rational number

The square root of 29 is an irrational number.

No, it is an irrational number. Sqrt of 2 goes on and on and on.

yes its a rational number because the square root of 4 is 2 and 2 can be put over 1

irrational

It could be either. For example, √9 is a rational number, whereas √2 is not.
