Every positive rational number and its negative pair?

Every positive rational number and its negative are the two square roots of the same positive rational number.


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.


What are all numbers than make a square?

All numbers can make a square. Every real number makes a positive real square. Every rational number makes a rational square. Every integer makes a perfect square.


Why are every positive rational number greater than every negative rational number?

It is because of the way in which positive and negative numbers are defined.


Is a additive inverse of any rational number a negative number?

The additive inverse of EVERY positive rational number is a negative number.


Is every rational number negative?

No because they can also be positive numbers


What is the relationship of rational numbers and real number?

The set of rational numbers is a subset of the set of real numbers. That means that every rational number is a real number, but not every real number is rational. The square root of 2 is an example of a real number that isn't rational; that is, it can't be expressed as the quotient of two integers.


Is every integer a rational number or is every rational number an integer?

Every integer is a rational number.


Rational numbers who square roots are whole numbers?

Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.


Why every irrational number is also a rational number but not every rational number is a natural number?

Every irrational number is NOT a rational number. For example, sqrt(2) is irrational but not rational. A natural number is a counting number or a whole number, such as 1, 2, 3, etc. A rational number is one that can be expressed as a ratio of two whole numbers, which may be positive or negative. So, -2 is a rational number but not a counting number (it is an integer, though). Also, 2/3 is a rational number but not a whole, counting number or a natural number.


What square numbers are even and which square numbers are odd?

What 2 numbers would be the square root of 53?

Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.


Do positive number have negative square roots?

Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.


If you take the square root of an irrational number.Will it be irrational too?

Certainly. Otherwise, there would be a rational number whose square was an irrational number; that is not possible. To show this, let p/q be any rational number, where p and q are integers. Then, the square of p/q is (p^2)/(q^2). Since p^2 and q^2 must both be integers, their quotient is, by definition, a rational number. Thus, the square of every rational number is itself rational.


Every rational number is a real number?

Yes it is, but not every real number is a rational number


Is every number a rational number?
