Here the formula is;
(a3 + b3) = (a + b)(a2 - ab + b2)
So, (a3 + b3)/(a2 - ab + b2)=(a+b)
In the given question a is taken as 768 and b as 232.
Therefore,(a+b)=768+232=1000.
(a3 + b3) = (a + b)(a2 - ab + b2)
So, (a3 + b3)/(a2 - ab + b2)=(a+b)
In the given question a is taken as 768 and b as 232.
Therefore,(a+b)=768+232=1000.
