I think it's 1/a ^-2, but I'm not sure.

a^0 = 1
a^0 / a^-2
= 1 / a^-2
= a^2
Remember that your final answer should have positive exponents.

a^0 /a^-2 = 1 / (1/a^2) =1 * (a^2/1) = a^2

a^0 /a^-2
=1/a^-2
=1/(1/a^2)
=a^2#

Given a^0 /a^-2.
Which has the greater number of factors of "a", the numerator of the denominator?
The numerator, since the exponent 0 is greater that the exponent -2.
How many more factors of "a" are in the numerator?
2. Which is the exponent of the simplified expession
of a^0 /a^-2.
That is, a^0 /a^-2 =a^2.

No, the simplest form is a^2.
To wit: a^0/a^-2 = 1/a^-2 = (1/a^-2)(a^2/a^2) = a^2/(a^-2)(a^2) = a^2/a^(2 - 2) = a^2/a^0 = a^2 QED.

a^0 is 1
Now, any number to a negative power, is the same as 1 over that number to the positive power. So, in this case you have:
1/a^-2 or a^2

a^0/a^-2
anything to the 0 power is one so:
=1/a^-2
to make a negative exponent positive flip the fration:
=a^2/1=a^2

when you divide a number that has a same base, subtract the exponent
a^ (0 - (-2))
= a^2
