(xy^3n)^2+(xy^6)^n(xy^3n)^2+(xy^6)^n(xy^3n)^2+(xy^6)^n(xy^3n)^2+(xy^6)^n=x^2y^(6n)+x^ny^(6n).(xy^3n)
(xy^3n)^2 +(xy^6)^n
(xy^3n)^2 +(xy^6)^n
(xy^3n)^2 +(xy^6)^n
(xy^3n)^2 +(xy^6)^n
=x^2y^(6n)+x^ny^(6n).
(xy^3n)^2 +(xy^6)^n
=x^2y^(3n^2)+x^ny^6n
(xy^3n)^2 +(xy^6)^n
=x^2y^6n+x^ny^6n
=x^2y^6n*[1+x^(n-2)]
(xy^3n)^2 +(xy^6)^n
=x^2y^(3n^2)+x^ny^6n
(xy^3n)^2 +(xy^6)^n
=( x^2 * y^6n ) +( x^n * y^6n )
=(x^2+ x^n)*y^6n
(xy^3n)^2 +(xy^6)^n
