Sprout · Answer

So if x^3=9 is your equation, what do you think you need to do first?

Sprout · Answer

Well it's quite simple. In order to get the answer and x by itself you must take the cube root of the x^3 and 9. When you do that, x=2.08

Yes, as sprout said. This is the answer rounded to the nearest 100th.
