Every positive rational number and its negative are the two square roots of the same positive rational number.
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.
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.
It is because of the way in which positive and negative numbers are defined.
The additive inverse of EVERY positive rational number is a negative number.
No because they can also be positive numbers
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.
Every integer is a rational number.
Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
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.
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.
It is a irrational number. Because the square root of every imperfect square is irrational number.
No because as for example the square root of 25 is 5 which is a rational number
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.
Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.
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.
Yes it is, but not every real number is a rational number
No but every integer is a rational number and numbers that can be expressed as fractions are also rational numbers
0 is a whole, integer, and rational number. O is whole number because a whole number is every positive number
They are every number you can possibly get when you divide one positive whole number by another one, or one negative whole number by another one.
Every rational number can be expressed as a fraction. It's what rational means- a number that can be expressed as a ratio (fraction) of integers.
the answer is opposite for apex users and its true
No. Every rational number is not a whole number but every whole number is a rational number. Rational numbers include integers, natural or counting numbers, repeating and terminating decimals and fractions, and whole numbers.
No. "Pi", "e", and the square root of 2 are all real and irrational.
