yes its a rational number because the square root of 4 is 2 and 2 can be put over 1
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, 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.
Yes because the square root of 4 is 2 which is a rational number
[ square root of (4.1) ] is irrational. But [ square root of (4) ] is rational.
The square root of 16 is 4, which is a rational number.
The square root of 16 is 4 which is a rational number
is 4 a rational number
It is rational.
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.
