What is the square root of -1?
Answers:
i.
i is a special number that does not exist in the standard number line (such numbers are called 'imaginary'). You can think of it as being the same distance away from 0 as 1 is, only at a 90 degrees angle away from the line between 0 and 1.

i
its impossible u cant have a sq root of a negative number

says it is invalid Q try this square root calculator
1i :]
No real value. Mathematicians creatd im aginary numbers.
the answer is i.
I think it must be 1
undefined!
plus or minus 'i'
the square root of 1 is i
Square roots of negative numbers are imaginary and not real numbers. sq. root of -1 is denoted as i to enable math operations.

Its 'i' according to the complex numbers theory

the square root of -1 is i.
i, which is an imaginary number
-1.0000
The square root of -1 is i, which stands for imaginary.
square root of -1 is iota represented as "i".
square root of any negative no. is an imaginary .
green_meklar's conception of the number line is perfect for bringing imaginary numbers into focus. The conventional (real) number line is one-dimensional. If you think of the imaginary number line as being 90 degrees from the real one, and passing through 0, you get a visualization that serves for real-world engineering problems involving imaginary numbers.
You might like to know these fun facts:
i^1 = i (obviously)
i^2 = -1 (already established above)
i^3 = -i
i^4 = 1
i^5 = i
i^6 = -1
i^7 = -i
i^8 = 1
etc.
A couple of couple of centuries ago (maybe even before that) that was consider impossible or with no answer.
Until . the day . a person (obviously bored) decided to define a symbol as the answer of the square root of -1.
The symbol that is used today is i (the first letter of the word "imaginary") and it was given by Leonard Euler. i and its multibles -i, 3i, 3.4i, etc, are named imaginary numbers because they are a creation of human imagination. They have a meaning only as even roots of real numbers.
The answer will be i.
the square root of -1 is i which is by defenition one of the 2 solutions to the equation x^2 = -1, the other solution being -i. Similarly, the square root of -9 is 3i, and so on.

IT'S Square Root(-1) is = i
i
There is no unique square root of -1.
i is defined such that i^2 = -1, but there are many other answers. For example, (-i)^2 is also -1, so sqrt(-1) could also be -i. i^6 = -1, so sqrt(-1) could be i^3.
And so on. There are infinitely many solutions to x = sqrt(-1). i is defined to be one solution (and the most basic, for many reasons).
i was not invented because someone was bored. It was invented because it is very useful.
i = sqrt(-1)
i^2 = -1
u can't have the square root of a negative number because what you square 2 get the square root of a number, must contain the same sign when squared, 2 of the same signs multiplied by each other is always positive.
there is no square root of -1
