## Can square roots be rational numbers?

Oh no, there is always an odd exponent.

So it could not have been made by squaring a rational number.

This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number.

In other words, the square root of 2 is irrational..

## How do you find out if a square root is rational or irrational?

Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).

## 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.

## Is the square root of 15 Irrational?

Answer and Explanation: The square root of 15 is not a rational number.

## 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.

## What number has the square root of 69?

## Is the square root of 67 a rational number?

67 is a prime number, so in particular has no square factors. So its square root is irrational and not simplifiable.

## Is 69 a square number?

Is 69 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. … Thus, the square root of 69 is not an integer, and therefore 69 is not a square number.

## Is 0 a rational number?

Zero Is a Rational Number As such, if the numerator is zero (0), and the denominator is any non-zero integer, the resulting quotient is itself zero.

## Is 5 a rational number?

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

## Is 2/3 an irrational number?

For example 3=3/1, −17, and 2/3 are rational numbers. … Most real numbers (points on the number-line) are irrational (not rational). The rational numbers are those which have repeating decimal expansions (for example 1/11=0.09090909…, and 1=1.000000…
