" 9."(a-b)^(3)+(b-c)^(3)+(c-a)^(3)=

((a-b)^(3)+(b-c)^(2)+(c-a)^(3))/(9(a-b)(b-c)(c-a))=?

(5a-7b)^3+(7b-9c)^3+(9c-5a)^3

If a+b+c=27 then (a-7)^(3)+(b-9)^(3)+(c-11)^(3)-3(a-7)(b-9)(c-11)=

(5a-7b)^(3)+(9c-5a)^(3)+(7b-9c)^(3)

The value of [{(a^2-b^2)^3+(b^2-c^2)^3+(c^2-a^2)^3}/{(a-b)^3+(b-c)^3+(c-a)^3}] = (1) 3(a+b)(b+c)(c+a) (2) 3(a-b)(b-c)(c-a) (3) (a+b)(b+c)(c+a) (4) 1

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(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)
