Question

Simplify. Remember to use absolute - value notation when necessary. If a root cannot be simplified, state this.
-3 √ -1000

Answer 1

√ -a = √ (-1*a)=√ a√ -1=√ a*i

Answer 2

I have -30i √ 10 and i am told that You can multiply something by itself 3 times and get a negative, so this does not result in an i for the radical.

Answer 3

I am lost with what is being asked

Answer 4

hmm... i^2 = -1
-1000 = -10^3
but the root is square, so I don't see how this could help
