What do you get when you multiply positive 3 by itself ?
(You get 9.)
What do you get when you multiply negative 3 by itself ?
(You get 9 again.)
The square root of a number is something which, when you
multiply it by itself, gives you the number.
When we multiplied positive 3 by itself, we got 9.
So positive 3 is a square root of 9.
When we multiplied negative 3 by itself, we got 9 again.
So negative 3 is also a square root of 9.
Every positive number has two square roots. They're both the
same digits, but one is positive and the other one is negative.
Of course it is. 'a' can be any positive or negative number, and 'b' is its square.That's no problem.What is difficult is for 'b' to be a negative number in the same equation.No real number for 'a' can produce a negative 'b'.
It is positive.
This is not possible, because any number squared would be positive, not negative.
This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.
No. The square of a positive number is positive; the square of a negative number is also positive; and the square of zero is zero. If you want to square a number and get a negative result, you need complex numbers. For example, the square of 2i is -4.
The square of a positive number is positive. By the way, the square of a negative number is also positive.
There are two possible answers because if you square a negative number, you will get a positive answer.
No. There is no real number which multiplied by itself forms a negative number.A negative times a negative is a positive, and only a positive times a negative is a negative.However, in calculus there is an "imaginary value" (called i ) which represents the square root of -1.Square roots of larger negative numbers are represented by the square of the absolute value times i .
The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.
The product of two negative numbers is a positive number. Ergo, the product of the square of a number is equal to the square of its negative equivalent.
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.
If you square any real number it will always be positive.
The square of a number is always two numbers multiplied together. A positive times a positive is always positive, and a negative times a negative is always positive.
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.
A positive number times a positive number is always positive. A negative number times a negative number is always positive. Therefore, any square number will be positive. Any number to the fourth power (a square times a square) will always be positive. And so on.
The square will be positive.
Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.
Any positive integer has two square roots, one positive number and one negative number. This is because a negative number multiplied by a negative number is equal to a positive number.In this instance, the square roots of 36 are 6, and -6.
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.
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.)
A positive number has two square roots, its principal (positive) root and its negative root. This is because a negative number multiplied by a negative number equals a positive number. In this instance, the square roots of 256 are 16 and -16.
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.
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
No. Negative three squared is POSITIVE nine. The square of ANY number is positive, because if you multiply a negative number by a negative number, the result is positive.
