```										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
