simplify (-3 sqrt(-1000))
-------
Factor -1000 into two factors where one is the largest possible perfect square.
That would be -100*10
----------------------------
= -3sqrt((-100)(10))
-------
Write as the product of the square roots:
= -3*sqrt(-100)*sqrt(10)
-------------------------------
Take the square root of the perfect square factor:
= -3*(10i)*sqrt(10)
---
Multiply:
= -30i*sqrt(10)
