<em>This is cube root (hence the </em>
).

So:

We know that
, so this doesn't work.
We also know that
, so this works.
Therefore the cube root of 27 is 3.
Hope this helped!

The answer would be B, since the other two just have to equal 100.
Simplified
2/5x-5-1/3
2 x -5 - 1/3
5
-10/5 - 1/3
-2 - 1/3
-7/3
