Prove that (a+b+c)^(3) =a^(3)+b^(3)+c^(3)+3(b+c) (c+a) (a+b)

Prove that (a+b+c)^(3)-a^(3)-b^(3)-c^(3)=3(a+b)(b+c)(c+a) .

Prove that (a+b+c)^(3)-a^(3)-b^(3)-c^(3)=3(a+b)(b+c)(c+a)

Prove that (a+b+c)^(3)-a^(3)-b^(3)-c^(3)=3(a+b)(b+c)(c+a) .

the value of the determinant |(0, b^(3)-a^(3),c^(3)-a^(3)),(a^(3)-b^(3),0,c^(3)-b^(3)),(a^(3)-c^(3),b^(3)-c^(3),0)| is equal to -

Factorize: (a-3b)^(3)+(3b-c)^(3)+(c-a)^(3)
