" 6."3a^(3)b-243ab^(3)

3a^(2)b-243ab^(2)

Factorise : 3a^3b-243ab^3

Simplify the following: (6) (i) (a^(3)b^(2)c-ab^(3)c)-(3abc^(3)-a^(3)b^(2)c)-(4ab^(3)c+2abc^(3))

(a+b)^(3)-3ab(a+b)

if a-b=6,ab=20. find a^(3)-b^(3)

a^(3)+3a^(2)b+3ab^(2)+b^(3) divided by a^(2)+2ab+b^(2) is

The product (a+b)(a-b)(a^(2)-ab+b^(2))(a^(2)+ab+b^(2)) is equal to: a^(6)+b^(6)(b)a^(6)-b^(6)(c)a^(3)-b^(3)(d)a^(3)+b^(3)
