I still can't tell what you mean.

You say "cube".  But "cube" is "third power"

Do you mean this?:

4sqrt%287%29%2B3sqrt%287%29-8%5E3%2A7.

If so then 

7sqrt%287%29%2B8%2A8%2A8%2A7

7sqrt%287%29%2B3584

Or did you mean "cube ROOT"  There is a HUGE HUGE difference
between "cube" and "cube root"

If you meant "cube root" then

4sqrt%287%29%2B3sqrt%287%29-8root%283%2C7%29

7sqrt%287%29-8root%283%2C7%29  

And that's as far as it can be taken.
