([3y+4)^(3)],[(a+b)^(3)+b^(3)+3ab(a+6)]

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

If (a ^(2) + b ^(2)) ^(3) = (a ^(3) + b ^(3)) ^(2) and ab ne 0, then ((a)/(b) + (b)/(a)) ^(6) is equal to

Prove that: (a+b)^(3)=a^(3)+b^(3)+3ab(a+b)

Prove that: (a-b)^(3)=a^(3)-b^(3)-3ab(a-b)

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))
