What is the square root of minus 1 (-1) .?

Question

I'll give a prize to the first correct answer.

Answer 1

In reality, you are not allowed to have a square root of a negative number. In algebra though, there is a special creation specifically used, i (yes, the lower case letter "i"). This signifies the square root of -1, which is in reality a part of the imaginary numbers set.

Answer 2

1

Answer 3

In mathematics, a square root of a number x is a number whose square (the result of multiplying the number by itself) is x.
THEREFORE SQUARE ROOT OF 1 IS 1
The square of any positive or negative number is positive, and the square of 0 is 0. Therefore, no negative number can have a real square root. However, it is possible to work in a larger number system, called the complex numbers, in which negative numbers have square roots. his is done by introducing a new number, called the imaginary unit, which is defined to be a square root of -1 This number is usually denoted by i (sometimes j)
THEREFORE SQUARE ROOT OF -1 IS i

Answer 4

-1

Answer 5

square root of minus 1 is

"i" in physics

"j" in engineering

Answer 6

1 squared is 1, therefore 1 is the square root of 1!

Answer 7

2 cases (sq. root of x) minus sq. root of (2x+a million) = a million Or 4x -- 4sqrt{x(2x + a million)} + (2x + a million) = a million^2 Or 6x = 4sqrt(2x^2 + x) Or 36x^2 = 16(2x^2 + x) Or 4x^2 -- 16x = 0 Or x(x -- 4) = 0 giving x = 0, 4

Answer 8

You didn't give enough info on the level of your math class.

If your math course never gets to the level of imaginary numbers, then the answer is "no square root."

If your math course covers imaginary numbers, then the answer is "i".

Answer 9

one

Answer 10

It's called i
