Every number has two square roots. You can't say the positive one, as making the square root of minus one either positive or negative makes -1 positive.

As long as choose one and stick to it, it really doesn't matter. More precisely, the complex numbers, C, are defined as R[x]/(x^2+1), he polynomial ring on R moded out by the ideal generated by the polynomial x^2 +1. Then i is identified with the image of the polynomial x under the quotient map.

The square root of -1 is really an imaginary number. The symbol for the square root of -1 is an italicized i.

i is defined as the square root of -1, but -i is also a square root of -1.
There really is no "the" square root of a number. Like you said there are two. When someone says "the square root," they are referring to the positive. when someone says "the square root of -1," that person is referring to i.

The square root of -1 is the imaginary number i.

no it doesnt because the square of -1 is called an imaginary number
because if you multiplied -1 by-1 it would still be positive one so there cant be a real square root of -1

That is simple Algebra II. You should know that the answer to the square root of -1 is not a real number or an imaginary number, or an italicized i

Not all numbers can be explained, but still must be used in order to calculate things.
"i" is the imaginary number used to represent this "square root of -1"
Search wikipedia for imaginary numbers for more info.

the square root of -1 is an imaginary number represented by the letter i...i takes the place of that number

The square root of negative one is defined as the imaginary unit, called 'i'. It is used to form complex numbers and has other mathematical applications.

you can not get answer for the square root of minus one,
It is impossible unless you use imaginary number (i)
