equation

Q2 no solution ? except (0,11) ?

but how can i solve it bcz ans = 0
it is in 1st quadrant...

ok (0,11) isnt in first quadrant right ???

yup der will be no solution

see the reason is , Fermat's last theorem

according to this theorem ,

no 3 integers a,b,c where each > 0 ,

can satisfy the eqn aⁿ+bⁿ=cⁿ

for n >2

And i guess this question has been asked on this theorem only

check this http://en.wikipedia.org/wiki/Fermat's_Last_Theorem

actually this question is from FIIT-JEE QUIZ......
here we use
x^{3}-y^{3}=-1331 and the factorise
(x-y)(x^{2}+xy+y^{2})=-1331
here both x and y are Integer so
(x-y) and (x^{2}+xy+y^{2}) both are integer

thanks for 2 one....
in Question (1) I got no solution but ans=1 solution.
