Because (K)B/(K)A = K(B-A) and any number divided by itself = 1 .

By definitions,x^0 = 1 for any non-zero number xalso0^x = 0 for any positive xSo, if 0^0 was defined, then the first definition would say it was equal to 1 and the second that it was equal to 0.There is a more detailed but complicated explanation which relies on limits but I hope this will suffice.
x to the n divided by x to the n is 1. By the law of powers x to the power n divided by x to the power n is x to the power (n minus n), ie x to the power zero. Things which are equal to the same thing are equal to each other. Therefore x to the power zero = 1. (Unless x = zero!)
The inconsistency is the following:Any number raised to the power zero is equal to one.Zero raised to any power is equal to zero.
Any number to the power of zero equals one.
Any non-zero number, raised to the zero power is equal to 1.
