Answer:
C: 1 / 7^2
Step-by-step explanation:
Here there are two exponentials with the same base (7).
To find the product, write the base (7) again, and form the exponent by combining the two exponents:
7^(3 - 5) = 7^(-2), or 1/49. None of the given possible answers match this. Answer C is closest: 1 / 7^2.
