The square root of negative 40 is: 6.324555 i
Yes, as is the positive square root.
it is impossible to get the square root of a negative, since the definition of a square root is something times itself. example: the square root of 16 is 4 because 4 x 4 = 16. and a negative times a negative is a positive, so the square root of a negative is impossible. however, you can do the square root of 121 (which is 11) and make the 11 a negative. 11 x 11 = 121 and -11 x -11 = 121 but you could make 11 negative after the fact, if that is what you wanted to do.
The negative square root of 324 is -18. In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. Since the square root of 324 is 18, the negative square root would be -18.
square roots of a negative number are imaginary, where i = square root (-1) sqrt (-2500) = sqrt (2500) i = 50 i
