Question

m^3n^-6p^0 simplify expression use positive exponents

Answer 1

n^-6 should be written   n^(-6).  This is equivalent to    

 1
-----
n^6

Also, p^0 is equivalent to 1.

Thus, 
                              m^3 (1)         m^3
M^3n^-6p^0   =   -------------- = ------------
                                n^6              n^6

and this could be written in the alternative form (m / n^2)^3, or


          m
      ( ------- )^3
         n^2
