What is the square root of a negative 1?
Unit Imaginary Number
The square root of minus one √(−1) is the “unit” Imaginary Number the equivalent of 1 for Real Numbers. In mathematics the symbol for √(−1) is i for imaginary.
Is the square root of negative 1 undefined?
The square root of a number y is defined to be the value x such that x2=y. However for any real number x x2≥0. When we say that the square root of a negative number “doesn’t exist” we mean that there is no real number solution.
What is the square of (- 1?
Answer: The square root of minus one √(−1) is the “unit” Imaginary Number. Therefore it doesn’t exist.

Why is negative 1 squared negative?
The answer is 1. The calculator said -1 because of the way calculators handle inputs. When a calculator sees it breaks it down in an odd way. Instead of how a person would interpret it as squaring negative one a calculator interprets it as taking 1 squared and returning its negative.

What is a negative square?
Yes you can square a negative number. … 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.
What is a negative square root of 81?
Explanation: 81=9⋅9 then the square root of √81=9 . Because the double multiplication for the same sign is always positive the square root is also valid with the other sign 81=(−9)⋅(−9) then √81=−9 and we can say that √81=±9 .
What is a negative square root of 100?
Every positive number has two square roots and the radical sign indicates the positive one. We write √100=10 . If we want to find the negative square root of a number we place a negative in front of the radical sign. For example −√100=−10 .
Is the square root of negative 100 rational or irrational?
Therefore the square root of 100 is rational.
Is a negative square root a real number?
Can a negative square root be an integer?
Negative numbers don’t have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can’t be written as the quotient of two integers.

Who invented the square root of negative one?
Bombelli was able to use his rules for operations with complex numbers to solve the cubic equations that produced an expression that contained a square root of a negative number.
Is a negative squared still negative?
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. If we find the square of a negative number say -x where x > 0 then (-x) × (-x) = x2.

What’s the value of root 3?
1.732
The value of √3 is approximately equal to 1.732. This value is widely used in mathematics. Since root 3 is an irrational number which cannot be represented in the form of a fraction. It means that it has an infinite number of decimals.
Are all square roots Plus or minus?
Why some people say it’s true: That’s exactly what I was taught in school: when you take a square root the answer is always “plus or minus” some value.
Why is square root positive and negative?
We denote the positive root (which we often call the square root) by √a . The negative solution of x2=a is −√a (we know that if x satisfies x2=a then (−x)2=x2=a therefore because √a is a solution so is −√a ). … And for it to be a square number both the nos . have to be same.
How do you add a negative square root?
What is a root of 1?
The square root of 1 value is: √1 = 1. As 1 is a real number and the square of any number is positive we can assume that the square root of 1 is 1 itself. Representing this mathematically we get the following: sqrt(1) = √1.
What is square rooting?
A square root of a number is a value that when multiplied by itself gives the number. Example: 4 × 4 = 16 so a square root of 16 is 4. Note that (−4) × (−4) = 16 too so −4 is also a square root of 16. The symbol is √ which always means the positive square root. Example: √36 = 6 (because 6 x 6 = 36)
How do you find a root of a number?
- Estimate a number b.
- Divide a by bn–1. If the number c returned is precise to the desired decimal place stop.
- Average: [b × (n-1) + c] / n.
- Repeat step two.
