You cannot divide any number having it's denominator as 0. That is so because, 0 * anything = 0. So, when you have a number like 5/0, you don't have an answer because 0*5 = 0, etc. Also, 0/0 is also undetermined. Because 0 * Any number = 0. Therefore 0*2=0; 0*3=0, etc. Therefore you cannot have a definite answer. As for 0^0, it is equal to 1. You can check in calculator. Any number raised to the power 0 = 1. Hope this helps.
