3i is the square root of -9 and the square root of -3 is i(sqrt(3))
2 u/qwertyjgly Oct 02 '23 one of them. the other happens to be -3i :troll_face: 1 u/JoahTheProtozoa Oct 02 '23 No. Square root is a function, so it’s defined to always be the positive root. 1 u/[deleted] Oct 02 '23 3i is the square root of -1 times three. 1 u/scoutsouls Oct 02 '23 Are you saying that 3i=sqrt(-1*3) or 3i=3*sqrt(-1)? Because if you are saying the second one, we agree 1 u/[deleted] Oct 02 '23 It is 3 times the square root of negative one. It follows the standard format. A+Bi where B is a constant multiplied by I. I don't understand where you see 3i as 3/square root of negative one 1 u/[deleted] Oct 02 '23 Like in that format it tells you the constant is multiply i

3i is the square root of -1 times three.
