" 6."8(a+b)^(3)+27(b+c)^(3)

Factorise : (i) 9a^(3)-27b^(3) " " (ii) a^(3)-343 " " (iii) a^(3)-(27)/(a^(3)) " " (iv) 1+8a^(3) " " (v) (a+b)^(3)-(a-b)^(3) .

Factorise : 8a^(3) - 27b^(3)

If a - 2b + 3c= 0 , state the value of a^(3) -8b^(3) + 27c^(3)

If a^(2) + b^(2) + c^(2) + 27 = 6(a + b + c) , then what is the value of root (3) (a^(3) + b^(3) - c^(3)) ?

Factorise : (8a^(3))/(27) - (b^(3))/(8)

If a + 2b + c= 0 , then show that: a^(3) + 8b^(3) + c^(3)= 6abc
