Yes, but it is not the case that one is the square root and the other is its opposite. Both are equal square roots with the other one being its opposite.

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.

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

Yes.

No - every positive number has a positive and negative square root. For example: sqrt(9) = 3 and -3, because 3 x 3 = 9 and -3 x -3 = 9.

yes...it is 1.41421356try it on a calculatorEvery positive number has a square root. In fact,every positive number has two of them.There is a square root of any number, but the square root of most numbers is not a whole round number. The square root of 2 is 1.41421

The square root of a positive number results in a positive number. For example, the square root of 25 is 5. * * * * * Not true! There are two real square roots for every positive number: one positive and one negative. -5 is as much a square root of 25 as +5 is. However, the positive root is the principal root and so is often presented as the only root.

Yes. It's 9. The square root of every positive real number is a real number.

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.

Every positive number has two square roots: one negative and one positive. So negative sqrt(7) < negative sqrt(3) < positive sqrt(3) < positive sqrt(7)

For the same reason that the square root of ANY negative number is not a real number.Real numbers are positive, negative, or zero. * The square of a positive number is a positive number. * The square of a negative number is a positive number. * The square of zero is zero. In other words, in no case will you get a REAL number whose square is a negative number. The square roots of negative numbers are said to be "imaginary" - a name given for historical reasons. They are just as "real" or "unreal" as the so-called real numbers, but the point is that they are a different kind of numbers.

Every positive number has TWO square roots. The principal square root is the positive number which, when multiplied by itself, gives the number in question. But its negative equivalent will also be a square root. For example, the number 4 has 2 as the principal sqrt but -2 is also a sqrt of 4

Technically, every positive number is a square in the real number system, but I assume you mean perfect square. And yes, 225 is a perfect square. 152 = 225

No, it does not; it could be a fraction (or, what amounts to the same thing, a repeating decimal), a negative number (in fact every strictly positive number has 2 square roots, one positive, one negative, such as the square roots of 25 are 5 and -5), an irrational number (like the square root of 2), or an imaginary number (like the square root of -49).

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.

The second root would be the negative of the principal root.

Yes, every positive real number has a real square root. If you would write your number in scientific notation, I could tell you what the root is.

Square root of 25 is 5 or -5. 5 X 5 is 25 -5 X -5 is also 25 A negative number multiplied by a negative number is always positive.

It depends on what you mean by an opposite. Every real number has an additive opposite but 0 does not have a multiplicative opposite.

Every positive number has a negative square root.For example, 2.25 has the square roots -1.5 (and 1.5)

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, you multiply a positive by a positive and get a positive. If you square 0 , get 0. Therefore, in no case is the answer negative. ( It is harder to explain why a negative times a negative is positive.)

The principal square root is a positive number which, when multiplied by itself, gives the original number. The second square root is the negative of the principal square root. So, for example, starting with 144. The principal square root is 12 because 12*12 = 144 and the second square root is -12.
