" of the chine "(p-q)^(3)+(q-gamma)^(3)+(gamma-p)^(3)

Factorise : (p-q)^(3)+(q-r)^(3)+(r-p)^(3)

(p-q)^(3)-(p+q)^(3) is equal to

Factorise (p-q)^3+(q-r)^3+(r-p)^3 .

If omega is an imaginary cube root of unity,then the value of (p+q)^(3)+(p omega+q omega^(2))^(3)+(p omega^(2)+q omega)^(3) is: (a)3(p+q)(p+q omega)(p+q omega^(2))(b)3(p^(3)+q^(3))(c)3(p+q)-pq(p+q)(d)3(p^(3)+q^(3))pq(p+q)

write the degree of the polynomial p^(2)q^(3)+p^(3)q^(2)-p^(3)q^(3) .
