The square root of 2 is irrational. In general, the square root of a positive integer is either an integer (if you take the square root of a perfect square), or it is irrational.
The square root of 4 is 2 which is a rational number
no it 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
The square root of 2, for example, is irrational.sqrt(2)*sqrt(2) = 2 which is rational.
Root 2 is appx. 1.414 and root 3 is appx. 1.732. There are many rational number between that. For instance: 1.5, 1.6, etc.
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. 2 is a rational number so they square root of 4 is rational.
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.
No, they are not.
no it 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.
Yes because 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
The square root of 2 is an irrational number
The square root of 2, for example, is irrational.sqrt(2)*sqrt(2) = 2 which is rational.
