## What type of number is square root of 64?

The positive square root of 64 is 8, and all integers are rational by definition.

To determine if a number is rational you need to see if you can write the value exactly as a fraction (or ratio) of two integers..

## Is 21 a real number?

Answer and Explanation: 21 is a whole number. Whole numbers include all positive integers.

## 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.

## What is not a real number?

A non-real, or imaginary, number is any number that, when multiplied by itself, produces a negative number. Mathematicians use the letter “i” to symbolize the square root of -1. An imaginary number is any real number multiplied by i. For example, 5i is imaginary; the square of 5i is -25.

## Which type of number is 15?

a composite number; its proper divisors being 1, 3 and 5. the number of supersingular primes. a repdigit in binary (1111) and quaternary (33). In hexadecimal, as well as all higher bases, 15 is represented as F.

## Is 20 rational or irrational?

## What is the perfect square of 80?

80 has a few factors that are perfect squares, namely 1,4 and 16 . For simplifying a radical we pick the biggest: √80=√16⋅5=4√5 .

## Is the square root of 80 a rational number?

Answer and Explanation: The square root of 80 is not a rational number.

## Is √ 13 an irrational number?

1 Answer. √13 is an irrational number.

## Is 64 a perfect square?

The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 …

## Is 6 a real number?

These are the set of all counting numbers such as 1, 2, 3, 4, 5, 6, 7, 8, 9, ……. ∞. Real numbers are the numbers which include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

## How do you identify real numbers?

The Real Number Line Points to the right are positive, and points to the left are negative. Any point on the line is a Real Number: The numbers could be whole (like 7)

## Is square root of 13 a whole number?

Actually, any positive number n has two square roots, namely √n and −√n . The notation √n denotes the principal square root, which is the positive one. So √13 lies strictly between 3 and 4 , so is not an integer, whole number or natural number.

## What number has a square root of 13?

## How do you represent root 13 on a number line?

Step-by-step explanation: Taking O as centre and OI as radius, draw an arc which cuts l in L. The point L represents square root of 13on the number line.

## Is the square root of 14 a rational number?

Explanation: The only square roots that are rational numbers are those who are perfect squares. … √14 =3.74, which is not an integer and therefore is an irrational number.

## Is √ 64 an irrational number?

ⓒ Since all integers are rational, the numbers −7,8,and−√64 are also rational. Rational numbers also include fractions and decimals that terminate or repeat, so 145and5.9 are rational. ⓓ The number 5 is not a perfect square, so √5 is irrational.
