What is neg 2 squared?
"This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result." – This, of course, is the exact opposite of what was asked, but it's the given response.
Is negative two squared positive or negative?
positive Answer: Yes. If a number is squared, it becomes positive. The square of a number can be found by multiplying the number by itself. Explanation: The product of two negative numbers is always positive.

What is the square of negative 4?
For real numbers, there is no number that multiplied by itself will result in a negative number. So that means that there is no real number solution when figuring out our solution.
What is 2i?
2i is an imaginary number because it has the form 'bi' Remember, 'i' is the imaginary unit and is equal to the square root of -1. Even though 'i' is NOT a variable, we can multiply it as if it were. So i • i gives us i2.
What value is 2i?
Answer and Explanation: The absolute value of the complex number, 2i, is 2. We can put the complex number, 2i, in the form a + bi by letting a = 0.
What number is 2i?
The quater-imaginary numeral system was first proposed by Donald Knuth in 1960. It is a non-standard positional numeral system which uses the imaginary number 2i as its base….Tabulated conversions.
| Base 10 | Base 2i |
|---|---|
| −4i | 1020.0 |
| −5i | 1020.2 |
| −6i | 1010.0 |
| −7i | 1010.2 |
Is 2i a real number?
All real numbers are complex numbers with zero for the imaginary part. 0 + 2i is just the imaginary number 2i. All imaginary numbers are complex numbers with zero for the real part.
Why is square 1 negative?
In math, i is defined as √-1, or the square root of negative one. A square root is the opposite of squaring, in the same way that subtraction is the opposite of addition, so the square and the radical (another word for root in this case) cancel out, leaving you with -1.
What does 2i equal to?
2i is an imaginary number because it has the form 'bi' Remember, 'i' is the imaginary unit and is equal to the square root of -1.
What is the square of (- 1?
Answer. Answer: The square root of minus one √(−1) is the "unit" Imaginary Number. Therefore it doesn't exist.
What is the square of 2?
The process of multiplying a number times itself is called squaring. Numbers whose square roots are whole numbers, (or more accurately positive integers) are called perfect square numbers….List of Perfect Squares.

What is x² in math?
What is x squared? x squared is a notation that is used to represent the expression x×x x × x . i.e., x squared equals x multiplied by itself. In algebra, x multiplied by x can be written as x×x x × x (or) x⋅x x ⋅ x (or) xx (or) x(x) x squared symbol is x2 .
What is this called X²?
Squaring a number is the same as raising that number to the power of two. The square function (ƒ(x)=x 2) is the inverse of the square root function (ƒ(x)=√x). Raising a number n to the power of 2 is called “squaring” because the resulting number n2 corresponds to the area of a square with sides of length n.
What is the absolute value of X²?
According to this definition the |x| is always greater than or equal to zero for all real numbers. |x + 2| ≥ 0 and |x + 2| < 0. This is because, by definition, the absolute value of x + 2 can be either x + 2 or − (x + 2).
What is x2 minus x2?
Any number minus itself is always zero.
What does 2x squared mean?
To evaluate the square of a product, we can use a well-known rule of exponents that tells us how to raise a number or expression to a power. Because 2x squared is equivalent to 2x raised to the second power, we can use this rule of exponents to evaluate 2x squared.
What does X² mean?
x squared is a notation that is used to represent the expression x×x x × x . i.e., x squared equals x multiplied by itself. In algebra, x multiplied by x can be written as x×x x × x (or) x⋅x x ⋅ x (or) xx (or) x(x)
What if absolute value is negative?
Since the absolute value of any number other than zero is positive, it is not permissible to set an absolute value expression equal to a negative number. So, if your absolute value expression is set equal to a negative number, then you will have no solution.
What do you call 2x²?
2x squared, denoted (2x)2, is equal to 4×2. In general, we can raise a product to a power using the following product rule for exponents: (ab)n = an…
