x to the power a divided by x to the power b is x to the power (a - b)

When a and b are equal then this is x to the power a divided by x to the power a, ie 1. x to the power (a - a) = x to the power zero.

Things which are equal to the same thing are equal to each other, so 1 = x to the power zero.
