When $$\sqrt[3]{-128}$$ is simplified, the result is $$a\sqrt[3]{b}$$ , where a is an integer, and b is a positive integer. If b is as small as possible, then what is a+b?

Hey there!

We need to factor out as much as we can in your cube root.

After we do, we have:

-4 times the cube root of 2.

I hope this helped,

Gavin.
