No; √2 is irrational.
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
Yes, because the answer is 3/2 which is a rational number.
And exponent of -2 represents the square root
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.
square root of 9 = 3 but 2, 17 and 23 are irrational numbers
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.
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
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 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
