Quick Answer: Which One Of The Following Number Has Rational Square Root?

Is the square root of one a rational number?

The number √−1 is not real.

Since the rationals are just a particular type of real number, it cannot be rational, either.

and so a2=−b2.

Since b2 is certainly positive, that means a2 is certainly negative, which is impossible..

Is the square root of 0.4 a rational number?

since the number is non terminating and non repeating therefore it is irrational number.

What is the difference between square and square root?

Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

Is 0.6 Repeating a rational number?

Answer and Explanation: Repeating number 0. ¯6. is not the irrational number, because we can convert that in the p/q form and they will be rational numbers.

Which of the following numbers has rational square root?

which one of the following numbers has rational square root ? Explanation : √0.09 = √9100 = 310 = 0.3, which is rational. ∴ 0.09 has rational square root.

What type of number is a square root?

The square roots of the perfect squares (e.g., 0, 1, 4, 9, 16) are integers. In all other cases, the square roots of positive integers are irrational numbers, and hence have non-repeating decimals in their decimal representations.

Is √ 3 an irrational number?

The square root of 3 is the positive real number that, when multiplied by itself, gives the number 3. The square root of 3 is an irrational number. … It is also known as Theodorus’ constant, named after Theodorus of Cyrene, who proved its irrationality.

Why is root 2 an irrational number?

Because √2 is not an integer (2 is not a perfect square), √2 must therefore be irrational. This proof can be generalized to show that any square root of any natural number that is not the square of a natural number is irrational.
