Express in terms of i

......
- √ ̅ -75
the "-75" is inside the radical sign I need full steps please and simplify

-
Are there two negative signs in the problem, as it appears there are?

- √(-75) =
- √((25)(3)(-1)) =
- (√25 * √3 * √(-1)) =
- (5 * √3 * i) =
(-5√3) i

If the problem is √(-75) rather than -√(-75), then the answer is just: (5√3) i

-
-sqrt(-75) = -5sqrt(3) i
