Question 952381
Consider what happens as exponents decrease:
{{{x^3=x^4/x}}},{{{x^2=x^3/x}}}, {{{x^1=x^2/x}}}, so {{{x^0=x^1/x}}}=1 
It is consistent with our description of exponential systems.
According to the law of exponents:
{{{x^a/x^b=x^(a-b)}}} so {{{x^2/x^2=x^(2-2)}}}={{{x^0=1}}}
While not exactly intuitive, we can see that it is consistent within the system.
