Answer 1

Answer:

7(a^3+b^3)

Step-by-step explanation:

343a^3+b^3

7a^3+b^3

7(a^3+b^3)

Answer 2

Answer:

(7a + b)(49a^2 - 7ab + b^2)

Step-by-step explanation:

343a^3 + b^3 = (7a)^3 + b^3

a^3 + b^3 = (a + b)(a^2 - ab + b^2).

                = (7a + b){(7a)^2 - 7ab + b^2}

                = (7a + b)(49a^2 - 7ab + b^2)

hope this helps you dear..
