Verified answer
Method - (1):Given that a + b + c = 0, then we know that a^3 + b^3 + c^3 = 3abc.
3.
Method - (2):
Given a + b + c = 0
a + b = -c
Now,
On cubing both sides, we get
(a + b)^3 = (-c)^3
a^3 + b^3 + 3ab(a + b) = (-c)^3
a^3 + b^3 + 3ab(-c) = (-c)^3
a^3 + b^3 + c^3 = 3abc
(a^3 + b^3 + c^3)/abc = 3
Hope this helps!
