Question

If a/b + b/a = 1 then what is the value of a^3 + b^3 = ?

Answer 1

a3+b3=(a+b)(a2-ab+b2). Eqn I
By solving a/b + b/a = 1
a2-ab+b2= 0 Eqn II

Putting Eqn II in Eqn I
Ans = 0 ( Zero )

Answer 2

ANSWER: 0
a3+b3=(a+b)(a2-ab+b2). Eqn I
By solving a/b + b/a = 1
a2-ab+b2= 0 Eqn II
Putting Eqn II in Eqn I
Ans = 0 ( Zero )
