can u let me know that how a^3 + b^3 + c^3 = 3.abc ? plz..
in which std. are u
a cube plus b cube plus c cube - 3abc=(a+b+c)*(...)
so if a+b+c =0
then a cube plus b cube plus c cube minus 3 ABC=0
hence a cube plus b cube plus c cube=3abc
i got it..thnks!!... it was just temporarily flushed away from my mind..
ok
