The problem does not specify whether all of the digits must be used or if just some of them can. 

The problem does not specify whether each digit can be used only once of if it can be repeated. 

 

You have to think of ways to get a 5. 

There are (10 divided by 2), (20 divided by 4), (40 divided by 8) and many other ways.

 

      (6 x 8) – 8 

      —————      This equals 5.  Just multiply it by itself 3 times and you get 125. 

             8   

 

                     (8 + 8 + 8 + 8 + 8)                (4 x 8) + 8                 (8 + 2)

       ditto       ————————     and     —————     and     ——–—        

                                  8                                    8                             2    

 

Those are four ways to get 5, and then just multiply it by itself 3 times, or mix 'em up.  You take it from here.
