=-10root3(150)

Explanation:

First, you'll need to know this fact:, rootn(ab)=rootn(a)*rootn(b), basically saying that you can split the big root sign into two (or even more) smaller ones.

Applying that to the question:
root3(-150000)=root3(150)*root3(-1)*root3(1000)

=root3(150)*-1*10
=-10root3(150)
