Stolyar I wpould go with A. As only -1 can satisfy both the modulous. Statement 2 isnt possible as there can be two values for X in that case 1 and -1.
Let me know the right answer. Agood question though
cheers

We discussed this matter many, many times, but you, guys, were not with us. Therefore, I say a gist of our long previous discussions: open up any school math book and make sure that 0^0 makes NO SENSE and so can be safely ignored. It is also helpful to memorize the definition of the zeroth power. Only then are you welcome to object.
Moreover, even if we admit that 0^0=1, this fact would not harm the answer A. I hope I have dismissed any further claims!!!
