I believe three to the power of negative one is -3
so then 9/-3=-3
i'd say the answer is -3
What is the value of 3²/3^-1?
I figured out that 3² is 9 and that divided by 3^-1 was 30, but that was not one of the listed answers. Where did I go wrong and what is the correct answer?
Thank you! :-)

The is how I would solve it
Since its division, you would subtract exopents
Since the numerator has a 2 as an exponent and the denominator has a -1 for an exponent I would subtract that
2-(-1) = 2 + 1
=3
3^3 = 27

If you have a negative exponent, just put a one on top of it to make it a positive.
Example:
3^-2 = 1/3^2
5^-3 = 1/5^3
7^-3 = 1/7^3
Example:
3^-2 = 1/3^2
5^-3 = 1/5^3
7^-3 = 1/7^3
