the answer is 0 because a3+b3= (a+b)(a2+b2-ab)
here the value of a2+b2 = ab
so ab-ab =0 so the whole answer becomes zero
here the value of a2+b2 = ab
so ab-ab =0 so the whole answer becomes zero

hello friend
answer is zero
as from a/b + b/a =1
a² + b²= ab
put this in the identity and get the answer be zero
hope it helps you
