Dear sundeep


x^(p/q) has q solution if you take complex value as well


here i will consider only real value


you can write x^(p/q)  as (xp)1/q


                                             or( x1/q)p


                             for example   (125)2/3


                                                    =(1251/3)2


                                                    =52


                                                    =25


           or you can solve it by using log


         take y=x^(p/q)


               logy=p/q log x


                       = p/q * some value


                       = some value


        take anti log


                   y= some value
