1. x^8+y^8
Not factorable with integers.
-----------
2. x^5-32y^5
= x^5 - (2y)^5
= (x - 2y)*(x^4 + x^3*2y + x^2*(2y)^2 + x*(2y)^3 + (2y)^4)
=
----------------
3. a^21+128c^7
= (a^3)^7 + (2c)^7
=
4. x^10+y^10
= (x^2)^5 + (y^2)^5
Similar to #3
------------
5. m^11-n^11
Similar to #2
= (m-n)*(m^10 ..... n^10)
