Yes, it is the principal square root of 4, and it is rational.
Yes because the square root of 4 is 2 which is a rational number
The square root of 2 is an irrational number

The square root of 48 is a rational or irrational
The square root of 2.56 is rational. This is because 2.56 can be expressed as 256/100, which simplifies to 64/25. The square root of 64 is 8 and the square root of 25 is 5, so the square root of 2.56 is 8/5, 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.
Yes, it is the principal square root of 4, and it is rational.
The square root of 4 is 2 which is a rational number
Yes because the square root of 4 is 2 which is a rational number
The square root of 2 is an irrational 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.
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
Yes, the square of any rational number is also a rational number.The square root of 2 is not a rational number.
yes its a rational number because the square root of 4 is 2 and 2 can be put over 1
Yes, because the answer is 3/2 which is a rational number.
No, they are not.
