Question

Is negative square root of 1 a irrational number

Answer 1

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.

Answer 2

No, you would get -1

Explanation:

Square root of 1 is 1

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