**DAILY DOUBLE**
Why is
x^0=1
Because the quotient rule tells us that when we divide powers of the same base we subtract their exponents. If the exponenents are the same on both powers and we subtract them we would get an exponent of zero.
We also know that when we divide a number by itself, it's always one.
1=(x^a)/x^a
1=x^(a-a)
1=x^0
