# 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.

### 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…

### What is the sign of the product of 11 negative integers and 2 positive integers?

The 2 positive integers don't affect the sign. Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end result is negative. The 2 positive integers don't affect the sign. Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end…

### Is every real number either a rational number or a irrational number?

Yes. A real number is any comprehendable number, from negative infinity to positive infinity. A rational number is any number that can be the answer to a division equation; an integer, fraction, or a decimal. An irrational number is any number that cannot be expressed as a fraction; such as exponents.

### The product of an odd number of negative factors is positive?

False. positive x positive = positive positive x negative = negative negative x positive = negative negative x negative = positive Every 2 negative factors provides a positive result, so if there are an odd number of negative factors, there are 2n + 1 of them which means the 2n would provide a positive factor to be multiplied by the final negative factor which gives a negative result.

### How many square roots can a positive number have?

Every positive number has two square roots, though the roots are not always whole numbers (or even rational numbers). The more obvious of each numbers roots is the positive one. The positive square root of 4 is 2, because 2*2=4. The positive square root of 5 is roughly 2.236068. The other square root of a number is the negative inverse of their positive root. This is because when two negative numbers are multiplied together the…

### 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.

### How do you know if a quadratic equation can be factored?

The answer depends on what the factors will be. For example, every quadratic can be factored if you allow complex numbers. If not, then it helps to use the discriminant. If it is positive, there are two real factors or solutions. If that positive number is a perfect square, then the factors are rational numbers. If not, they are real but not rational (irrational). If the discriminant is 0, there is one real solution. Lastly…

### Why is it impossible to get a negative answer when you square any number?

V kno that- x- is +. Now when u sqare a negative no it means occouring 2 times and cancel out each other. For example- -2 x -2=4 ============================ (a second answer.) Every real number is either negative, positive or zero. When you square a number, you multiply it by itself, so if you square a negative number, you are multiplying a negative by a negative which gives a positive. If you square a positive…

### What is negative exponent?

It's a number up and just to the right of the bigger first number. If its. 3 2 Then you multiply it like 2 times 2times 2 With negative exponent you switch it from negative to positive every other one starting with negative. We do this because a negative and a negative multiplied together equal a positive and a positive times a negative is negative. -123771

### Does every point on the real number line correspond to a rational number?

No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.

### What is the nonenegative square root of a number?

Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.
