Answer:
9/7
Step-by-step explanation:
with any negative power, we have to find the reciprocal of the base. in this case, it is 9/7. then, apply the exponent to the fraction. now, it is 9^1 over 7^1. we can just write it as 9/7 because if the exponent is 1, it is just the value of the base, so it is not written.
