No, it is an irrational number.
Sqrt of 2 goes on and on and on.
The square root of 4 is 2 which is a rational number
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 an irrational number is not always rational. In fact, the square root of an irrational number is typically also irrational. For example, the square root of 2, which is an irrational number, is itself irrational. However, there are exceptions, such as the square root of a perfect square of an irrational number, which can be rational.
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.
Yes, because the answer is 3/2 which is a rational number.
The square root of 4 is 2. 2 is a rational number so they square root of 4 is rational.
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 4 is 2 which is a rational number
Yes, the square of any rational number is also a rational number.The square root of 2 is not 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 root of 2 is an irrational number
No, they are not.
Yes because the square root of 4 is 2 which is a rational number
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.
Yes, because the answer is 3/2 which is a rational number.
yes its a rational number because the square root of 4 is 2 and 2 can be put over 1
