Is every rational number a perfect square?
No. Though every perfect square is a rational number, not every rational number is a perfect square. Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.
Is the square root of 4 irrational or 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.
Is square root of 4 rational?
The square root of 4 is 2. 2 is a rational number so they square root of 4 is rational.
Is a square root always an irrational number?
No; the square root of any rational number squared is that rational number. Examples: √(2^2) = √4 = 2. √((1/2)^2) = √(1/4) = 1/2
If a square root of a number is a rational or an irrational?
It could be either. For example, √9 is a rational number, whereas √2 is not.
Is every rational number a perfect square?
No. Though every perfect square is a rational number, not every rational number is a perfect square. Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.
Is the square root of 4 irrational or 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.
Is square root of 4 rational?
The square root of 4 is 2. 2 is a rational number so they square root of 4 is rational.
Is an imperfect square a rational number?
No. The square of 4√(2) is an imperfect square. But since it is = sqrt(2), it is not rational.
A short note on square root of 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.
Is the square root of 4 a rational or irrational number?

How can you multiply 2 irrational number to get a rational number?
The square root of 2, for example, is irrational.sqrt(2)*sqrt(2) = 2 which is rational.
Is the square root of 4 rational?
Yes because the square root of 4 is 2 which is a rational number
Is the square root of a number rational or irrational?
that depends on the number. sqrt(2) is irrational, sqrt(4)=2 is rational
