Explanation:

Since b2 is certainly positive, that means a2 is certainly negative, which is impossible. √−1=i is an imaginary number, not lying anywhere on the real number line. Therefore as others have said, it is neither rational nor irrational in the usual senses of those words.

No, you would get -1

Explanation:

Square root of 1 is 1

If the negative was IN the square root, it would be imaginary.
